Foreword

IN presenting this catalog for your consideration, we wish to call your attention to
some of its most distinctive features. No attempt has been made to prepare a
complete list of scientific laboratory apparatus and equipment as there are many
highly specialized forms of equipment to which only occasional reference is necessary.
This special apparatus is covered by separate pamphlets which are available at all
times. We have attempted to list all forms of standard equipment as well as those of
special design, for which there is a moderately general demand.

THIS CATALOG IS A COMPILATION OF EXCLUSIVELY AMERICAN MADE

GOODS AND IS A TRIBUTE TO THE PROGRESS MADE BY

AMERICAN MANUFACTURERS

We have elected to prepare a fairly complete catalog of convenient size, rather
than an encyclopedia of scientific apparatus, which would of necessity be so bulky as
to be unwieldy.

In the selection and arrangement of .descriptive data and illustrations, we have
been guided by the requirements of those who may have occasion to use the catalog.
We have made an attempt to simplify the work of ordering our merchandise, wherever
it has been possible to do so, without sacrificing accuracy or necessary information.

Each illustration shows either a standard type of apparatus or a characteristic
feature which may be adapted to your requirements.

As a general rule, the articles described in this catalog are carried in stock for
immediate delivery. Other apparatus can be promptly secured or made up at a
reasonable cost.

Reference to other catalogs will be understood by us and the specifications cor-
rectly interpreted.

The utmost care is observed in checking and packing goods for shipment, and
every effort is made to avoid breakage in transit. All claims for loss, damage or
breakage in transit should be promptly filed against the carrier. We will assist in
every way possible, the adjustment of such claims. Any complaints will be promptly
and cheerfully investigated and complete satisfaction is assured.

All prices are based upon actual market conditions and are subject to change
without notice. Fluctuations may be expected, but our prices will be consistent with
existing conditions over which we have no control.

The cost of containers and packing will be charged at cost. Acid bottles, cases,
^carboys and some drums are extra and returnable for full credit at our store or
warehouse.

Our terms of payment are NET CASH 30 days, F. O. B. Chicago.

Where no definite shipping instructions are furnished with order, we will use our
own judgment, and ship by shortest and cheapest route. All shipments are made in
compliance with Interstate Commerce Commission regulations. Parcel-post shipments
will be made wherever possible, with a small charge for insurance.

Conditions arising out of the war require our customers to obtain licenses for
the purchase of ethyl alcohol and certain chemicals classified as explosives. Whenever
such materials are ordered, it is imperative that certified copies of license accompany
the order, as shipments cannot be made until such certificates are received.

Our GLASS BLOWING DEPARTMENT is adequately equipped to repair and
make up all kinds of standard and special apparatus, either plain, graduated or ground.

Our BALANCE and INSTRUMENT REPAIR DEPARTMENT has been or-
ganized to inspect and repair any imported or domestic balances and instruments.
We take great pride in our ability to render this service and guarantee all work of this
nature.

We wish to thank our friends and customers for their past consideration and hope
that it will continue. We solicit all inquiries, and no order is too small to receive ©ur
most careful attention.

Our organization has been planned for SERVICE. It is at your disposal.

Faithfully yours,

A. DAIGGER & COMPANY.
Chicago, January. Nineteen-Nineteen.

FOR DETERMINATION OF ALCOHOL IN
BEVERAGES

ACCORDING TO FRITZ

This apparatus, known also as the NERBEROMETER, was especially designed
for the brewers and manufacturers of beverages and so-called "near" beers for the
determination of alcohol content. This apparatus is recommended at this time when
so many substitutes for beer are being produced on a large scale. We are prepared
to furnish this apparatus complete from stock, as well as the separate items which
make up the apparatus complete. The necessity for this apparatus has been brought
about by the stringent requirements of the law, limiting the percentage of alcohol
which these beverages (so-called "near" beers) are permitted to contain.

1011

The apparatus consists of a specially constructed copper still, gas heated, with a
copper condenser, water cooled. Under proper heat control, the distillate is collected
in the cylinder as shown above. An aliquot portion is withdrawn and the percentage
of alcohol read with an alcoholometer. The still and condenser are made of heavy
copper, water inlet and outlet on the condenser being made of lead pipe. All joints
are provided with rubber gaskets.

1011 Price complete as shown $40.00

For prices on all parts which are interchangeable, as flasks, pipettes, burners,
rubber tubing for gas and water, thermometers and so forth, \ see under alphabetical
classification throughout the catalog.

While it is impracticable to list all special apparatus required for
testing materials, we wish to call your attention to our special sec-
tions on Tar and Asphalt testing.

We are prepared to furnish any apparatus both in Metalware
and Glassware required on special tests, etc.

HOYT'S ELECTRICAL PENETROMETER

1072 HOYT'S — An electrically operated, automatic instrument for determining the

consistency of asphalt and similar substances by measuring the depth
to which a standard needle with a definite load will penetrate during
a definite period of time, at a given temperature.

FOR THE STANDARD TEST THE LEFT PUSH BUTTON IS PRESSED.
This releases the needle with attached weight and penetration instantly takes place.
After a lapse of exactly five seconds the needle is automatically reclamped and penetra-
tion ceases. The depth of penetration is read directly from the dial, each division of
which corresponds to 0.1 mm. downward movement of the needle.

FOR SPECIAL TESTS the instrument may be adjusted for any variation desired.
Either the 50, 100, 150, 200, 250, 300 or 350 gram test may be made with equal accuracy
and speed by a simple substitution of weights. The needle may be readily clamped or
released for special tests by means of a clutch. For periods of penetration other than
five seconds, the push button on the right may be used and any desired time may be
allowed for penetration, the period being controlled by the large minute dial at the top
of the instrument.

DESCRIPTION — The entire instrument is automatic and is operated by two
ordinary dry cells. It is enclosed in a mahogany case with glass sash, lock and key.
There is also a large drawer located in the base for keeping the testing pans, ther-
mometer and other accessories.

• ADVANTAGES — 1st, produces uniform penetration tests; 2nd, controls the
duration of tests; 3rd, applies uniformity of penetration weights; 4th, eliminates vibra-
tion during operation; 5th, insures absence of personal equation.

APPARATUS FOR WATER SAMPLING IN CREOSOTE OILS.

1084

SAMPLING OF CREOSOTE OIL IN TANK CARS AND STORAGE TANKS FOR
MAKING WATER DETERMINATIONS

"It is recommended as good practice that, in order to obtain accurate determinations
as to the percentage of water contained in creosote oil in tank cars and in storage
tanks, the principle of zone sampling be employed, and described in the 1916 report
of your Committee (Proceedings, Vol. 17, pp. 447 to 456) and that for the purpose of
obtaining zone samples an apparatus of the type illustrated in this report be used."

From Bulletin of the American Railway Engineering Association, Vol. 18, No. 195,
March, 1917.

This apparatus consists of a brass cylinder with a pointed, perforated bottom.
The holes in the bottom are closed by means of a spring valve, which can be opened
by means of a wire extending along the extended stem attached to the cylinder.
This stem is made in several sections, so that it can be used at any depth. The stein
is calibrated in feet and inches, thus facilitating the zone sampling. The apparatus is
as illustrated.

Capacity • • 200 grams

Sensitiveness 1/20 milligram

Diameter of Pans 2^ inches

Length of Beam 7 inches

Bearings Agate planes

Knife edges • • Agate

Capacity of bar and vernier . .50 Mgm. to 1/10 Mgm.

It is the regular No. 1105 Becker Balance equipped with chain, and gives direct
rapid reading without rider or small weights.

Polished mahogany case, front sliding frame, counterpoised. Mounted on black
plate glass.

After all the necessary large weights up to 50 milligrams are placed on the pan,
the weighing from 50 milligrams to 1/10 of a milligram can be concluded without
opening the balance or using the arrest, eliminating the necessity of reading and re-
placing all small weights or the handling of a rider with a consequent enormous saving
of time.

One end of the weighing chain is hung from an arm of the scale beam, and the
other end from a slide-block which is moved up and down on a vertical graduated
scale. As this block is raised, more of the weight of the chain is taken from the
beam and hangs from the slide-block which forms a stationary support for holding
the inactive part of the chain. As the slide is lowered a greater proportion of the
weight of the chain is transferred to the beam.

Price $175.00

base fitted with leveling screws. The stage, scale and hook are clamped
to the upright, all three being adjustable separately. The improved
mirror scale is graduated in millimeters. The pans are of aluminum
suspended on very sensitive springs. Two springs, a high and low ten-
sion, are included with each balance $25.00

Used for determining specific gravity of minerals, etc., and in laboratories of
rubber factories.

1187 IMPROVED CELERITAS TRIPLE BEAM LABORATORY BALANCE.

This balance is one of the most popular of our specialties. It has a
capacity of 111 grams, a sensibility of 0.01 gram, and reads directly on
the aluminum beam to 0.01 gram. The beam is engine divided and is
tested and adjusted at each division. The two lower weights are sup-
plied with spring clips to insure accurate setting. The weights do not
interfere, and they are attached to the beam so that they cannot be
lost. A milled head lifts the center knife edge from its bearing when
not in use. The stand is neatly enameled and is supplied with a leveling
screw, spirit level, and swinging support for specific gravity work. The
pan is movable and its hanger has an extra hook for specific gravity $17.50

Owing to the present regulation of platinum consumption by the Gov-
ernment officials, we have discontinued the furnishing of platinum fractions
almost entirely. In the place of fractional weights made of platinum we are
now supplying these made of Gold, Rhotanium and other non-oxidizing
metals. These weights have been tested very carefully and found to be ex-
tremely accurate. We recommend them to be equal in every respect to the
platinum fractional weights.

1593 BLOWERS, Crowell's Rotary Compressor or Vacuum Pump, Type "D." The

Crowell Type "D" Rotary Air Compressors are manufactured in
nine standard sizes of from four to three hundred and ninety cubic
feet free air per minute capacities and are designed for a working
pressure of twenty-five pounds or less per square inch. When usec*
as Vacuum Pumps, all sizes of this type will, under permissible
atmospheric conditions, exhaust to a vacuum of from twenty-nine
to thirty inches (mercury column). The action is simple, positive
and durable with a continuous intake and delivery of the air. No
valves, springs, gears or unbalanced parts are used or required in
the construction. The pressure or degree of vacuum is not de-
pendent upon high operating speeds and as no special foundation or
great amount of floor space is required, the installation and onera-

With Oil Box

1594

Without Oil Box

LABORATORY SUPPLIES AND CHEMICALS

tion is a comparatively simple matter. The Crowell system of lubrication as applied
to all standard Type "D" sizes, is positive and automatically controlled by the air
pressure or vacuum. The oil feed valves are adjustable to suit the grade of lubricant
used, and can be closed entirely when necessary. Rotates in one direction only either
for use as a Compressor or a Vacuum Pump, requiring no changes in the lubricating
system which operates from the outlet or pressure side under either compression or
vacuum. Connections should be made to the inlet or suction side for vacuum work
and it is also advisable, when using as a compressor, to run a pipe from the inlet to
such place where a clean supply of air is assured. The heads are provided with water
jackets for cooling, when necessary. The flow of water is regulated by the valve
which is fitted to the overflow or discharge pipe. "Crowell Rotaries" are also made in
other types, special sizes, etc., for lower pressures or vacuums as well as for higher
pressures up to 125 Ibs. to square inch, or practically absolute vacuums. Plain or
automatically controlled motor driven outfits supplied in all types.

2176 CALORIMETER, Standard— Parr's.

This instrument has been devised by S. W. Parr, professor of Applied Chem-
istry at the University of Illinois. The marked features of the method are accu-
racy, simplicity, ease and rapidity of manipulation. The results are absolute and
not relative. The operations are such as can be carried on by one not especially
skilled in laboratory processes. Oxygen under high pressure or any pressure is
not used. Sodium peroxide is used as the combustion medium.

The time consumed in conducting a test on a weighed and dried sample
should not exceed fifteen or twenty minutes. With this instrument a determina-
tion of the heat units has been made on the various types of fuel selected from
widely different sources, including coal, coke, lignite and oils.

The outfit consists of the apparatus as indicated in cut, including a fine
thermometer graduated to 1/20° F. A two-litre measuring flask, chemical recep-
tacle, measuring cup, 5-inch 100-mesh brass sieve with bottom, chemicals suffi-
cient for fifty determinations, including special chemical for petroleum, etc.,
pincers, ignition wire, reading lens and camel's-hair brush.

2177— PARR'S NEW PEROXIDE CALORIMETER BOMB.

A new and greatly improved form of bomb for the Parr
Standard Calorimeter has been devised which has marked
advantages over the old pattern. A summarized statement
of advantages for more convenient reference is given below:

1. A removable fusion cup, or crucible, is provided with
an extra cup for duplicating determinations. These cups are
made of a special alloy which is immune to the action of
the fused alkali. The materials making up the charge can be
weighed out and added directly to the cups, which may then
be transferred to the holders for use as desired.

2. The electric terminals are short and sturdy, and do
not become bent* or broken by use.

3. Provision is made by means of an air space about the
fusion cup whereby the cup is permitted to come to a red
heat, after which the surrounding water is brought into con-
tact with the cup for quick extraction of the heat. This high
temperature throughout the mass avoids the cooling eect
of metallic walls which are in contact with water, thus secur-
ing a complete combustion with all types of coals.

4. By use of the fusion cups a removable bottom is
avoided and the process of cleaning out the fusion is very
much expedited. The cups are short enough to readily go
into a small No. 3 or No. 4 beaker lying flatwise, in which
way the fusion is readily dissolved out without loss.

5. The electric contacts are simplified and made much
more convenient.

6. A simple additional accessory makes it possible to
use the fusion cups for sulphur determinations alone. This is
without doubt the ideal method for making a determination
of sulphur in all organic compounds and especially to be
recommended for use in determining the sulphur in coal.
See description following under No. 2179.

2179 PARR'S NEW SULPHUR BOMB.

sac

For sulphur determinations which are to be made inde-
pendently of the calorimetric process, a special apparatus,
as shown in Fig. 2D, has been devised. An adaptation
has been made of the same fusion cup as that used in the
calorimeter bomb (Fig. 2A). By reference to Fig. 2D, it
will be seen that the fusion cup (2AC) has a cover (7AC)
with a gasket (27AC), and a screw cap (5AC), by means
of which the container is tightly sealed. The lower half
of the fusion cup, however, is exposed, and by applying
heat to the bottom of the cup the charge is readily ignited.
After a moment, it is held under the tap for cooling, after
which the cup is removed and the fusion dissolved otft.
In this way the solution containing all of the sulphur as
sulphate may be made ready for precipitation in less than
five minutes and with no possible accession of sulphur from gas flames or other sources
of contamination.

Results obtained by this method are believed to be the most reliable of any, and
the time element is decidedly to its advantage.

, For organic halogens, to replace the ordinary Carius method in the determination
of chlorine, bromide and iodine, the use of this bomb will be found exceedingly con-
venient and expeditious.

2181 CALORIMETER— Parr's, Oxygen Bomb Calorimeter with "Illium" Bomb.

Not the lease among the achievements in the construction of oxygen bombs
of the Mahler-Atwater type is the doing away with the porcelain or platinum
lining as a result of the development of an alloy which is proof against the
solvent action of the acids generated in connection with the combustions.

The first successful bomb made of this metal has been in service for a
number of years and has been used in upwards of 2,000 calorimetric determina-
tions without giving any evidence of corrosion. Many of the determinations
were made parallel with a platinum-lined instrument, and throughout the series
there was every evidence of an exact equivalent in the behavior of the alloy
(Illium) bomb.

The calorimeter complete with bomb, water container, insulating vessel with
cover, stirrer and pulley, oxygen connection with gauge, needle valve and
couplings, octagon holder for bomb, with spanner wrench, one-half dozen cap-
sules of special alloy, reading lens and support, special ignition wire and gaskets.

2183 CALORIMETER— Parr's Adiabatic with "Illium" bomb.

Another form of Calorimeter, and that of the Adiabatic type, has just been per-
fected, and its operation in actual use has been so eminently satisfactory that it is now
being regularly manufactured for the trade. It is the completion of a design which has
been in process of development for some years by Professor S. W. Parr of the Univer-
sity of Illinois.

The adiabatic principle has been
secured, not by the use of the Dewar,
or vacuum arrangement, with its
somewhat questionable immunity
from variation, nor is use made of
any chemical or electrical method of
heating the surrounding water. The
principles involved are carried out as
follows:

A supply of hot and cold water is
automatically provided immediately
underneath the desk on which the
calorimeter is installed. This may be
drawn upon either to raise or lower
the temperature of the water in the
surrounding medium. By means of a
stop cock and overflow, hot water,
for example, can be instantly dis-
charged into the jacketing water. The
lag, therefore, is only that incident
to the stirring of the water and the
response as shown on the thermom-
eter occurs at once.

2185 CALORIMETER, Emerson's, one of the most modern bomb calorimeters for
determining the heating value of solid and liquid fuels.

The Bomb is made of steel, consisting of two cups joined by
means of a heavy steel nut. The lining is of sheet metal, spun to fit
the interior. The pan holding the combustible is usually of nickel
and so are the supporting wires. The fuse wire for general fuel
testing should be of platinum.

The Calorimeter jacket is a double walled copper tank. The
calorimeter bucket is of light sheet brass.

The Stirring Device consists of a propeller fitted shaft inclosed
in a vertical tube to facilitate its action in circulating the water. The
stirrer is mounted on a post on the calorimeter jacket as is the
thermometer holder. The motor is driven by a 110-volt circuit and
should be placed in series with a 16 C. P. lamp. If so desired, a
battery driven motor can be specified in ordering the apparatus.

The Oxygen Piping is especially strong and durable and is
designed for two cylinders. Other accessories such as iron plate
holder, swivel table, spanner or wrench are furnished with the outfit.

A pamphlet describing the instrument fully may be had upon

2191 CALORIMETER, The Riche Adiabatic.

The Riche Adiabatic Calorimeter is constructed along practical lines, capable of
standing the strain of continuous work. The inside walls of the cabinet are lined
with one inch pressed cork and on the cover in addition to the cork is a piece of half-
inch hairfelt, making a tight joint with the top of the vacuum cup. All fittings are
brass, heavily nickeled.

The rapidity with which results are obtained is a decided advantage. A complete
determination may be made in 10 to 15 minutes with an accuracy of (1) three calories,
thus saving from fifty to seventy-five per cent of time. The maximum time required
for reading is eight minutes.

The bomb is of the Mahler-Kroeker two valve porcelain lined type, guaranteed for
3,000 determinations, but it should be good for at least 8,000 combustions if proper
cafe is taken.

2193 CALORIMETER — Sargent's, for gas: The only apparatus conforming with the
suggestions of American authorities, being the most advanced type of instru-
ment for testing the thermal value of inflammable gases. It has the following
advantages:

(1) The discharge water is weighed to one-hundredth of a pound instead
of being measured in a graduate. (2) The discharge water is switched auto-
matically from one receptacle to another after each one-tenth of a cubic foot
of gas is burned. This eliminates errors due to hand manipulation. (3) Inlet
and outlet thermometers are on the same level so that they can be read almost
simultaneously. (4) A Wet Pressure Governor controls the pressure of the
gas entering the burner and a constant pressure is easily maintained by means
of adjustable weights. (5) To maintain a constant flow the inlet and outlet
pipes are provided with wiers. A graduated quadrant valve regulates the
amount of water used. (6) Since a determination can be made every three or
four minutes, a curve of the heat value extending over any length of time may
be plotted. (7) The heat value of the gas is determined directly in B. T. U.
(8) The Bunsen burner has two tips and is adjustable for gas having 100 to
1500 B. T. U. per cubic foot. (9) The calorimeter is made of copper and brass
and is handsomely nickel-plated. (10) The Wet Test Gas Meter is made of
heavy brass and tin and has a water level indicator outside of the gauge glass.
The meter is graduated to 0.001 cubic foot.

2198 CARBONATE APPARATUS— Barker. For determining the percent-

The principle upon which the apparatus is based is that of a
hydrometer which takes account of the law that when an object (the
hydrometer) is immersed in a liquid, it is buoyed up by a force equal
to the weight of the liquid displaced by the object. In this apparatus
the carbon dioxide gas released by the sample decreases the weight.
The apparatus consequently rises in the water in which it is immersed,
recording on the graduated scale the percentage of carbonates from
which gas escaped.

Every hydrometer is thoroughly tested before leaving the factory
and is accompanied by a certificate.

CEMENT TESTING APPARATUS

2229

2229 -CEMENT TESTING MACHINE, Olsen's New Automatic Shot Form. The

principal advantages of this machine are as follows:

The machine is automatic to its full capacity and is not touched from
start to finish of test. The instant the briquette breaks, the breaking lead is
read on the dial of the scale.

The load is applied with absolute smoothness, and impact from falling
shot is eliminated.

The cut-off on the shot kettle is practically instantaneous. All shot that
has escaped from the kettle has already done its work and the column of
falling shot in the air when the specimen breaks is therefore weighed as it
should be.

A new grip which brings the strain uniformly on the specimen is used.

The briquette hangs clear of the frame of the machine, giving plenty of
room for the hands when adjusting specimens.

This is widely used and thoroughly satisfactory outfit; 1,000 Ibs. capacity; length,
24 inches; height, 26J4 inches; weight, 50 Ibs.

2249 CENTRIFUGE, Purdy Electric, with Adjustable Speed Regulator.

In order to regulate the speed of the Centrifuge more delicately than is possible
with the regular device attached to the instrument and to obtain any rate of speed
desired within the scope of the motor or to keep the instrument at a fixed speed where
the current varies or the load is increased, a speed regulator is necessary. It is often
important that an entire series of experiments should be carried on with an absolutely
uniform speed. This is mostly not possible without a speed regulator, owing to the
varying strength of all electric currents. Again, extremely fragile sediment must often
be handled with medium speed, while very light sediments require the highest speed to
produce sedimentation.

The speed regulators can be supplied with any of the Purdy Centrifuges, Nos.
2238-2243 inclusive, for either the direct or alternating 60 cycle current of 100 to 115
volts at an additional cost of $9.50

THE PURDY CENTRIFUGE FOR THE 220 VOLT DIRECT CURRENT

We supply the Purdy Centrifuge for the 220 volt direct current in all cases with

2347 COLORIMETER, Kennicott-Sargent. It is especially recommended on

account of the rapidity of operation while maintain-
ing the highest standard of efficiency possible with
the color method. The standard and unknown solu-
tions come in contact with glass only. The apparatus
consists of a wooden camera which exhibits on a dark
background the pictures of the sample and the stand-
ard side by side in the form of two large round discs
of color by means of light transmitted through the
sample and standard by means of swinging mirrors.
The body of the camera is of the correct shape and
focal length, enabling the observer to place his face
close to the mouth of the instrument whereby all side
lights and distracting rays are eliminated. The glass
parts consist of a tubular reservoir provided with a
glass plunger. From the bottom of a graduated glass
chamber there extends a glass tube connected with
the bottom of the reservoir, also a corresponding
tube for the unknown solution to be tested.

The complete apparatus as illustrated $20.00

2347a COLORIMETER, Kennicott-Sargent's, modified by Campbell- Hurley. In

this colorimeter the method of comparing the colors
is similar to that used in a half shade polariscppe,
the field consisting of a circular disc of light divided
vertically into two parts. The comparison tubes are
those of the well-known Kennicott-Sargent instru-
ment in which the unknown is placed in the left hand
tube while the color is matched by raising or lower-
ing the level of a standard solution in the right hand
tube by means of a glass plunger working in the
attached reservoir.

A person looking through the eye piece observes a
single field divided vertically by an almost im-
perceptible line representing the contact point of the
hemispheres of the two comparison tubes.

HESS-IVES TINT PHOTOMETER

2347b

2347e

The Ives' Tint Photometer is an instrument for comparing different shades and
hues of light colored materials or liquids with each other and with fixed standards, in
order to differentiate and classify them, and give them numerical expression. It is
adapted particularly, and far better than any other existing means or device, to tests
of paper-pulps, different hues and grades of white and tinted paper, transparency of
waxed and similar papers, color of oils and other liquids, qualities of flour as shown
in prepared baked samples, white pigments in oil or turpentine, cottonseed meal,
etc., etc.

The Ives' Tint Photometer is used like a telescope, presenting to the eye a
circular field with vertical hairline central division, one side of which is filled through
a slit with light directly from a standard white magnesia block, while the other is
filled through another slit with light from the sample to be compared, measured and
given numerical expression. The slits are adjustable, with a reading-scale, and the
light coming through them is spread evenly across the respective half fields by means
of a patent revolving optical mixing-wheel between the slits and the field lens.
Especial attention is called to the fact that personal color equation and even a marked
degree of color blindness do not affect the readings obtained with the Tint Photometer.

In order to assure definite and constant illumination of standard and sample a
"daylight" lamp must be employed.

For other special purposes, such as measuring the transparency of waxed and
similar papers and substances, or light colored liquids in long tubes, special fronts
are provided, at an additional cost of from $5 up.

METHOD OF DETERMINING

Lubricating Oils. The color of
Lubricating Oils is determined by
placing a 4-oz. bottle of oil under
examination in one of the circular
compartments of the instrument. In
he opposite compartment place a
l-oz. bottle of Water White Gaso-
line or Distilled Water. Then place
one of the standard glasses in the
slot, and close the slide. The instru-
ment should be taken to a window,
where the observer, looking through,
can compare the color of the oil
with the standard glass.

Filtered Cylinder Oils. To determine the color of Filtered Cylinder Oils they must first be mixed
with Water White Gasoline in the proportions of 15% Oil and 85% Gasoline. Then proceed as described
for determining color of Neutral Oils.

CRUSHERS

Ready for use. Opened for cleaning.

2466

NO. 1 OR SMALL CASE CRUSHER, HAND AND POWER

2466 CRUSHER, Case. The Case Improved Laboratory Crusher is designed to meet
the constantly increasing demand for a strong Laboratory Ore
Crusher with greater capacity than any other similar Crusher. We
unhesitatingly recommend it as being the strongest, fastest and best
Laboratory Crusher ever built.

The above cuts represent in detail the Combination Hand and Power Machine,
which has the essential features of strength and speed, and, at the same time, requires
the least power of any Crusher, for work accomplished, on the market.

This Crusher is the most easily cleaned Crusher manufactured. It can be so thor-
oughly cleaned that there is no possibility of salting. The simple turning of a large
hand nut loosens the stationary jaw, which may be removed and brushed off. This
large hand nut serves a double purpose — it is sufficiently large so that it gives great
leverage and the jaw does not work loose when the Crusher is in motion. The movable
jaw is provided with loop handle cast on top, by which the jaw is lifted out of the
socket for cleaning.

Another special feature with reference to the jaws is that both are pivoted from a
center, so that when one end becomes worn it may be reversed and you receive double
wear from the Crusher plates.

The Case Crusher is shipped with three replaceable shims or liners which fit be-
tween the stationary jaw and the Crusher frame. By inserting these shims, your prod-
uct may be ground to any fineness.

This machine is lubricated by means of grease cups in place of the old method of
using oil, which means that it will run for days with very little attention.

The capacity of the Crusher of this character depends on the nature of the product
to be crushed. This machine will take rock or soft substances 2l/2" in diameter re-
ducing so that same will pass through a 10 mesh sieve or finer at the rate of from 50 to
150 pounds per hour.

The shaft is 1^2" in diameter, driven by a 9" pulley with a 2^4" face, at from 450 to
500 revolutions per minute, and requires 1 H. P. for general use. Opening of jaws,

All parts of this machine are made on jigs in exact duplicate, consequently replace-
ments can be had at minimum expense. In other words, the Case Crusher is a thor-
oughly standardized machine.

Floor or bench space required for small size: 14j4"x21". Net weight: 140 Ibs.
Shipping weight: 165 Ibs.

Kindly compare all of the above good Crusher features when in the market for a
Crusher and make no mistake.

Price, f. o. b. Factory ........ . ............................................. $50.00

While it is impossible to list all types of Jaw Crushers, Grinders, etc., in
the limited space allotted to these machines, we are listing the representative
ones for Crushing, Grinding and Pulverizing. We can furnish any special or
ordinary type of Crusher or Grinder of various capacities, either hand or power
driven.

LARGE SIZE LABORATORY CRUSHER, POWER ONLY

2467 CRUSHER, Case, large size for power only. In construction, it is an exact
duplicate of the smaller Crusher, having all the essential fea-
tures, but is designed for greater capacity and heavier work —
for such samples as are required by large mills and smelters.
This machine, like the smaller, is easily cleaned by removing
the stationary jaw and lifting the movable jaw by handle cast
at the top for this purpose. For machine of this size, we
recommend a 2-horse power motor and a speed of 400 revolu-
tions per minute. The shaft is lli inches, driven by a 14
inch diameter pulley with 4 inch face. Loose pulley made
slightly smaller so as to take strain off the Crusher bearing and
shafting when not in use. The Crusher jaws are 10^4x4^
inch face. Jaw opening: 3J4x4j4 inch. Floor space: 27x28

are 3 inches wide and open at the top 1^4 inches. Forty
pounds of the hardest rock may be crushed in one hour, 20
per cent of this will pass a 60-mesh sieve. By tightening
the adjustment and crushing again, it will all pass a 60-mesh
or finer sieve. Weight, 100 pounds, packed for shipment $18.00

2475

THE CASE IMPROVED PULVERIZER
Open for Cleaning

2475 PULVERIZER, Case.

Capacity — The capacity of the Case Grinder depends on
the hardness of the ore and the size of the ore fed
through the Hopper and the fineness to which it is
ground. In actual tests, we find the machine capable
of grinding 8 ounces of quartz, 92% of which passed
through an 80-mesh sieve, in 10 seconds; 5 pounds
sulphide ore in zy2 minutes, 84% of which passed
through a 120-mesh sieve.

Adjustment — Ore may be ground to any degree of fine-
ness desired, from 60 to 150 mesh by a very simple ad-
justment, consisting of a hand screw, which is fastened
to the rear bearing and acts on the shaft, controlling
the distance between the stationary and revolving disc.

We recommend a speed of 1,000 r. p. m., which requires
about 3 h. p.

EVAPORATORS

Waste products become by-products when properly handled. During the last quar-
ter of a century the Swenson Evaporator Company has been instrumental in the de-
velopment of a large variety of by-product industries. Such interesting instances as the
recovery and marketing of products from packing house waste waters, iron sulphate
from wire and plate mills, pickle solutions, etc., are examples of successes in which
they properly take a large share of credit.

The Swenson Evaporator Company have installations at several institutions of
learning throughout the country, among which the University of Michigan, Massachu-
setts Institute of Technology, and Armour Institute of Technology are the most noted
examples.
Your further attention is directed to the Swenson advertisement in the advertising: section.

One of several Swenson types employed in the Swenson-University of Michigan
Laboratory, where experiments with liquors in car lots can be made. These are the
only facilities of this kind offered to American industries.

VACUUM OVEN

2645/1 "The Standard F. A. C. Vacuum Oven has been designed with the idea of
affording a simple and compact vacuum oven which will give as uniform tem-
peratures as possible on the shelf. It consists of an iron casting of rectangular
sections with hinged front door, which is accurately counterpoised. The door
is made tight by a gasket and which can be lowered on opening the oven so
as to form a shelf on which samples may be rested. The oven contains but
one shelf which is heated from above as well as below by means of resistance
coils. Several thermometer holes are provided in order to ascertain definitely
the temperature at different points on the shelf. ' The entire oven is supported
by means of a 4" standard pipe which screws into the base of the oven and
which in turn is supported by being screwed into a blind flange of suitable
diameter which rests on the floor or work table."

Dimensions — overall — 15"xll"x8" high.

2709 FILTER PAPER, Whatman No. 30 (Dreverhoff No. 207; Munktell No. 0), a

single acid-washed paper of low ash content, rapid and re-
tentive. Very satisfactory for the filtration of Ammonium
Phospho-Molybdate, Barium Sulphate when properly pre-
cipitated, for volumetric Lime determinations and for general
quantitative work when the lowest ash is not important.

2710 FILTER PAPER, Whatman No. 31 (Munktell No. OB), a single-acid-washed

paper similar to No. 30, but more open in texture, making it
more rapid. On account of its extreme rapidity it is not
recommended for the finest precipitates. Suitable for the
very rapid filtration of gelatinous and large particle precipi-
tates, for volumetric determinations of Phosphates, for Sili-
con in Iron Analysis, and general rapid quantitative separa-
tions where the lowest ash weight is not essential. Extens-
ively used in Metallurgical Laboratories.

acid-washed paper of very low ash, all mineral matter having
been removed by treatment with hydrochloric and hydro-
fluoric acids. Filters rapidly and retains fine precipitates.
This is the standard double-washed grade for analytical pur-
poses. Excellently suited for Barium Sulphate when prop-
erly precipitated and filtered hot, also for Lead Sulphate, and
for crystalline precipitates, such as Magnesium-Ammonium
Sulphate, etc.

2712 FILTER PAPER, Whatman No. 41 (S. & S. No. 589, Black ribbon), a double-
acid-washed paper similar to No. 40, but more open in texture
and therefore filters more rapidly. Suitable for Iron, Alumi-
num, and other gelatinous precipitates which can be filtered
quickly and washed rapidly and easily. Widely used in deter-
mining Silicon in Iron and Steel Analysis.

2713 FILTER PAPER, Whatman No. 42 (S. & S. No. 589s, Blue Ribbon), a double-

acid-washed paper, similar to No. 40, but much harder and
extremely close in texture. On account of its close texture
it is recommended for use with the filter pump and as folded
niters where possible. Especially adapted for the finest pre-
cipitates which tend to pass through the filter paper, such as
Barium Sulphate when precipitated in cold solution, and in
general for precise analytical work where speed is not im-
portant.

acid-washed paper, of the same stock as No. 40, but having
been subjected to an additional chemical process which renders
it fat-free. Especially suited for the recovery of the ether
extract in the Roese-Gottlieb Fat Test, and in general for
any purposes requiring a fat-free paper.

paper of thinner substance and lower ash content than the
preceding numbers. It will retain the finest precipitates, but
is slightly slower in filtration than No. 40. No. 44 is recom-
mended for use when the greatest possible degree of accuracy
in quantitative work is required.

2715a FILTER PAPER, Whatman No. 50 (S. & S. No. 575), a paper specially hard-
ened by treatment with Nitric Acid. Very tough, will
resist great pressure, and retain the very finest precipitates.
Can be used repeatedly, the hard smooth surface permitting
precipitates to be scraped or washed off without injury to
the paper. Especially recommended for use with vacuum.
Suitable for very fine precipitates and for filtering corrosive
liquids such as Acids and strong Alkalies. Should be used
when it is desired to transfer a precipitate without ignition.
Widely used for filtering Biological products, as the hardened
surface prevents contamination of the filtered product by
particles of paper when scraped off. Can be used as a sub-
stitute for platinum cones, and as supports for large folded
. filters to prevent them bursting at the points.

FURNACES— HOSKINS' ELECTRIC

TYPE FD

These furnaces, Type FD, are designed for industrial and laboratory purposes.
Their construction eliminates all the shortcomings commonly found in wire-wound
electric furnaces. Attention is particularly called to the fact that all parts of this
furnace which require renewals are very easily accessible and can be replaced by the
operator himself. No part of this furnace need be returned to the factory when in need
of repairs.

The heating unit is surrounded by bonded kieselguhr, backed up with asbestos and
magnesia slabs. It is believed that this insulation is the most efficient that is available
and it is responsible for the low power consumption of this FD line.

The door of the furnace is of the sliding type and has an adjustable counterbalance,
which causes the door to remain open at any desired point or close automatically.

Construction — The heating element in these furnaces is of heavy Chromel "A"
wire, wound in spiral coils. The refractory, around which this wire is wound, has
spirally built ribs on its surface, which give the walls of the heating-chamber a greater
strength, and at the same time the spaces between these ribs act as grooves in which
the wire is wound and is thus automatically and properly spaced.

Temperature — The maximum safe operating temperature of the FD Furnace is
1830° F. (1000° C). The minimum temperature that can be maintained with the
standard rheostat is about 900° F. (480° C.). With special rheostats, they can of course
be operated at lower temperatures, with the exception of the Tube Furnace.

Operation — Hoskins Furnaces, Type FD, are built for 110 or 220 volt circuits, alter-
nating and direct current. Special windings will be made for any voltage between 100
and 300. All styles require the use of a rheostat, which is the only auxiliary apparatus
required.

291G(a) 291G(b)

2916 (a) FURNACE— Hoskins' Electric (Type FD), No. 101. Crucible chamber style,

as shown; may be titled on its side and used for a small muffle. Particularly

for making crucible combustions, incinerations and melting alloys within

temperature range of furnace. Includes 6 feet twin connector, cord and

TYPE FB— FURNACES

110-220-440 VOLTS

Hoskins Type FB Electric Furnaces are for work requiring temperatures up to
1100° C. (2000° F.). They are especially adapted to heavy duty or continuous operation,
and are capable of twenty-four-hour-per-day service if required. The heating units of
all Type FB Furnaces can be removed and replaced by the operator within a few
minutes.

Temperature — The maximum working temperature of all Type FB Furnaces is
1100° C. (2000° F.). The minimum temperature at which the rheostat-controlled fur-
naces can be maintained (after having come up to heat) varies between 316° C. (600° F.)
and 536° C. (1000° F.) for the different designs. The Types FB 204 to 235 inclusive can
be maintained at any temperature between that of the room, in which the furnace is
operating, and 1100° C. (2000° F.).

Operation — Type FB Furnaces operate on low voltages (10 to 67.5 volts), for
which reason they are best adapted for use on alternating current circuits in connection
with a transformer. They are regularly supplied for use on 110, 220 or 440 volt, 25 or 60
cycle lines, but can be supplied for other voltages and cycles at prices which will be
quoted on application. Temperature regulation of the Types FB 204 to 235, inclusive,
is by means of regulating transformers; the types of smaller power in-put are con-
trolled by means of rheostats.

Power Consumption — None of the furnaces described in this bulletin, of course,
draws the full load except when heating up. Once up to heat, they operate on a greatly
reduced current, in some cases less than half the maximum.

is of great convenience and economy where a large number of carbon
determinations are to be made, using the direct combustion method. Five
carbon combustions can be run simultaneously, and in approximate terms,
at one-fifth the attention, one-third less space and correspondingly lower
up-keep cost than that represented by five single tube furnaces of the
same capacity.

The combustion tubes are heated by direct radiation from the "hair-
pin" heating units, between which the tubes lie. Temperature regulation is
accomplished by means of a regulating transformer. This furnace is also
made in the FD type. See No. 2916(e).

2916 (k) FURNACE CORES, Alundum. For the construction of small wire resistance
electric furnaces Alundum refractory cores meet the criteria of the most
efficient material for this purpose. The resistor should be spiralled and
wound and then embedded in Alundum cement. Thus, fully protected, the
wire does not corrode under the most severe conditions, since the Alundum
mixtures are chemically inert. In addition to this the core has high heat
conductivity and does not become an electrical conductor even at the
highest temperatures obtained in the furnace.*

FURNACE CEMENT— HYTEMPITE

Hytempite is a high temperature fire brick cement which has proven of great value
in the laying of firebrick and in the general repair of all types of furnaces, retorts,
ladles and so forth. It is a scientifically compounded refractory plastic material and
forms a lasting union between the materials to be joined, retaining its strength regard-
less of the heat to about 3100° F. It is better than fire clay because fire clay and water
has no binding strength. It does not loosen with expansion or contraction. Hytempite
withstands the cutting action of the flames and is especially recommended for oil
furnaces. It is largely used, also, as a coating or wash or to smoothen and harden the
surface of a lining to protect it from abrasion.

In 25, 50, 100 and 225 pound kegs and in barrels of 800 pounds. Also furnished
in ton lots with prices on application.

Below is illustrated a typical test of a firebrick broken, repaired with HYTEMPITE
and then re-broken. Note the last illustration, showing location of new fracture.

The Break (see note)

The Test (see note)

NOTE.— The brick illustrated was broken and repaired with HYTEMPITE, sub-
jected to a high temperature, and upon being tested fractured as shown, proving the
repair stronger than the brick structure.

Prices on application.

2916(e) FURNACE CEMENT. Alundum cement is recommended for use in con-
nection with Alundum muffles, cores, and wherever a refractory cement
with high thermal conductivity is desirable. It has the same general
proprieties as the refractory article and is furnished in the form of a
dry powder, which, when mixed with sufficient water to make a thick
paste, is ready for application. The material should be allowed to dry
and finally heated to a good red heat. In burning, the heat should be
raised as high as possible, as this will give the cement a body similar
in character to the refractory article.

LABORATORY FURNITURE

The laboratory is becoming more and more a factor in education, in the profession,
and in the trades. We furnish laboratory furniture not only for educational institutions,
but for private experimental and clinical laboratories, such as meet the needs of
physicians, commercial chemists and pathologists. We use the best grade of lumber
in the manufacture of our furniture. It is kiln dried by the most modern process known.

We furnish all the plumbing complete to the floor line ready to be screwed
together and connected Plans showing the exact location of the different outlets
should be -obtained before the floor pipes are laid. All sinks and gutters furnished in
connection with our laboratory furniture are made from lJ4-inch soapstone. This stone
has no equal. It will withstand the action of acid better than any other known sub-
stance.

While it is impossible to list all types of Laboratory Furniture
we list at least representative ones of Laboratory Tables for Students'
and Professors'. use for Bacteriological and Industrial purposes and
Chemistry Fume Hoods and Balance Tables. We also are capable
of furnishing Museum Cases and Cabinets of various kinds, for Fun-
nel and Burette Supports, etc. (See under alphabetical classification

2963-1 GENERATOR— Parson's Automatic, for H2S, CO2 and H. This is the most
popular generator for large requirements; used by the majority of edu-
cational laboratories throughout the country to distribute HzS to labora-
tory classes.

The apparatus is perfectly automatic in action, and the refuse is auto-
matically removed, while the pressure is almost constant. Only fresh acid
comes in contact with the solid reagent, so that the full strength of the
acid is utilized. There are no stoppers or valves, the apparatus being con-
trolled entirely from the exits. It requires practically no attention, is
easily cleaned and refilled without being taken apart. Forty outlets flow-
ing at the rate of two bubbles every second can be furnished by one
apparatus. Most instructors prefer exits for use with hydrogen sulphide
to be situated in the hoods; the rubber connection containing a small
piece of capillary tubing, being concealed behind a block, screwed to the
wall; thus the student sees only a rubber tube protruding from a hole, and
being unaware that his supply is limited by the size of the capillary, has
no means of increasing the supply. Waste is thereby avoided.

2973 Gas Regulator, Roux, Bi-metallic, designed to meet the demands for an accurate
regulator without the use of mercury or glass in its construction. It is
particularly well adapted for Incubators and other Ovens where a constant,
even temperature is desired. Inlet tube E is connected by means of rubber
tubing to the gas supply; the outlet D is connected in the same manner
with the burner under the incubator. A is a set screw to regulate the flow
of gas, and B a lock nut; C is a small set screw for pilot light. Diameter
of tube, 1 inch.

Small, 10 inches long 11.00

Large, 12 inches long 12.00

2973 (b) Gas Regulator, Greenman's, made entirely
of steel. The gas entering at "C" must pass
the valve "H" before passing to the burner
through "D", excepting that a small quan-
tity, determined by the screw valve "J"
passes through the by-pass "I" to main-
tain the pilot flame. The mercury in the
tube "A" when expanded raises the valve
"H" against the conical valve seat "G" and
the valve is prevented from falling too far
by the pin at "O." The volume of the mer-
cury is controlled by the rod "K," which
is held in place by the screw "L." By ad-
justing the rod "K" and the screw valve
"J" an extremely accurate control of the
gas supply and the temperature may be
maintained. The slightest increase in the
volume of the mercury contained in the
tube "A" produces a considerable differ-
ence in the height of the mercury in the
2973-3b passage "F" and the float "H," which is

about two-thirds submerged in the mer-
cury, is carried upward and closes the valve
"G." The brass tube into which the regu-
lator is to be inserted should be filled with
glycerine 12.00

3072 Instantaneous Water Heater, giving instantly a continuous supply of water
at any temperature, from boiling to lukewarm, free from the products
of combustion, and suitable for all purposes. Designed to hang over
lavatory bowl or sink. In two sizes; large size, height 19 inches,
projection from wall 8 inches; small size, height 18 inches, projec-
tion from wall 6 inches. This water heater is more especially in-
tended for the lavatory and the general odd work of laboratory and
domestic purposes where hot water is constantly wanted quickly.
The gas supply should be from a 5^-inch pipe. It will work equally
well, but at a proportionately slower rate, with any gas supply, how-
ever small. The speed at which the water runs rules its temperature.
It will heat 1 pint of water per minute from 50 to 130 degrees Fahren-
heit, or will boil 15 quarts per hour. The duty of the larger size is
about double that above given. It is not designed for baths. Con-
sumption of gas: large size, 40; small size, 20 feet per hour.

Note. — The light must be applied to the gauze before the gas is
turned.

Recent Improvements. — A pilot light attachment, which auto-
matically lights the burner when the gas is turned on; also a coupled
gas and water tap, operated by a hand-wheel, a turn of which lights
the burner and gives an immediate flow of warm water.

connected with a water tap, hot water in three seconds after the gas
is lighted, either boiling, hot, warm or cold, the water being pure and
fit for cooking purposes. In one minute it will deliver sufficient hot
water for washing hands. It is simple, cheap, not liable to get out
of order or wear out. Gas supply required, ^-inch clear bore pipe and
tap, to obtain the maximum power, at which it consumes about 60
feet per hour. It will work at a proportionate rate with any gas sup-
ply, however small. If frequently used for long periods in a confined
room, the products of combustion should be carried away.

3228 Hydroeik, an improved form of the Mason's Hygrometer. Consists of two
thermometers (wet and dry bulb) mounted upon the outer edge of a
chart, which has been plotted from new and corrected tables pre-
pared under the direction of the United States Weather Bureau.

3232 The Mason Hygrometer, while invariably recognized as the most accurate

and satisfactory of the many forms of hygrometers in use, has never
enjoyed the popularity which its merits deserve, owing to the annoy-
ing necessity of reference to complicated tables for determining the
Relative Humidity and Dew Point corresponding to the difference in
degrees between the wet and dry bulb thermometers at different tem-
peratures.

The Hygrodeik chart, while complicated in appearance, is simplicity itself,
and obviates entirely the use of tables for temperatures between 20°
and 200° F. Full instructions with each. $10.00

3503 MOTOR, Series Intermittent Service, alternating and direct current. Machines
or devices that have a fixed load can be successfully driven by series type
motors, but where the load varies and it is necessary to maintain a con-
stant speed at all times, regardless of the load fluctuation, this type of
motor will not answer the requirements fully. For uses such as driving
small fans, air pumps, centrifuges, etc., these little motors will be found
preferable.

As our Ovens are made in our shops, v/e are prepared to make them in
any shape, size or design that may be desired. We use Heavy Copper for all
Ovens coming in contact with water or the moisture from steam, when steam
heated. All Sheet Metal Ovens other than those which must be of Copper
are made of American Ingot Iron. This material lasts much better than the
Russian Iron or plain steel which pits. For the outer coverings we use the
Hard finished asbestos product, Transite, which is the best known insulator.

3582(c) OVEN, Sargent's Electric, patented Jan. 6th, 1914; electrically heated and
automatically controlled, it may be set for any desired temperature
between 50°C and 160°C, and is accurate to within 1°C. The chamber
of the oven is 10 inches high, 12 inches wide and 10 inches deep. The
oven is made of an asbestos compound and bound with metal and may
be connected to the usual lamp socket by a plug and cord. The
units are of the replaceable type and in case of accident may be renewed
in a few moments without the use of tools. The working chamber
has three shelves, of which the two upper are of approximately the
same temperature and are usable for constant temperature work, such
as coal analysis, while the bottom shelf being close to the heating
units, may be used for rapid evaporations where the temperature is
of no consequence, as in inorganic work.
Arranged for 110 or 220 volts, direct or alternating current.
Price, complete with thermometer, six foot cord and plug and

directions for operating $27.50

Extra heating units, each 1.00

Resistance wire on spools, sufficient for rewinding many heating

units. Per spool 1.50

In ordering, please state voltage desired.

3583 OVEN, Celeritas, Electric; constructed of Asbestos Board, and with
heavy brass binding, finished in keeping with our regular stand-
ard apparatus. The regulation is positive and the control within
one degree. The range at which the Oven can be used is from
50 degrees to 200 degrees Celsius. Consumption is 5 amperes.
Can be used with ordinary socket on either alternating or direct
current. A feature is that the contact points are outside the Oven.
This eliminates any possible danger when using a combustible
substance. •

Heating units are independent and can be renewed, but this will
hardly be necessary so long as ordinary care is taken of the Oven.
Electrical heat does not require draft. In fact, these changes are
detrimental to all heating units. Proper ventilation at the top is
all that is necessary.

For 110 volts, either Direct or Alternating Current, size, 10x10x12

inches wide, with 6 feet cord and plug $40.00

Can also be furnished for 220 Volts.

With Accurate Temperature Control. Patented in the United States and European
countries. Approved by the National Board of Fire Underwriters.

The FREAS' ELECTRIC OVEN has become widely and favorably known through-
out the world as the most accurate, reliable and durable electric oven for constant
temperature purposes. The oven after once set for the temperature desired is always
ready for use, and can be depended upon for continuous unattended operation. It is
easily adjusted for the desired temperature by simply turning a milled head screw.

DEKHOTINSKY TRIPLE WALLED DRYING OVENS

ELECTRICALLY HEATED AND REGULATED

3583-4

3583-4 OVEN, drying, triple walled DeKhotinsky.

Distinctive Features.

1. A new bimetallic thermo-regulator (patent applied for), which is actuated
by a difference in temperature of 1/°C. (This does not mean control
of temperature throughout the oven chamber to 1/4° C, but within the space
adjacent to the regulator.) Charts made with a recording thermometer actually
show less than a degree of variation through periods of 24 hours.

2. Location of the heating elements in the base of the oven beneath the false
bottom — instead of in the oven chamber — where they are shielded by an iron
deflector, preventing radiant heat from striking the lower shelf.

3. An air circulating system which reduces the difference in temperature between
the top and bottom shelves to less than a degree C. instead of 12 to 20
degrees, as usually found.

4. The DeKhotinsky standard system of heating, by which extra heating units
may be thrown into or out of the circuit to obtain any desired temperature up
to the maximum.

5. Replaceability of heating units by the user from outside the oven in case of
burn-out, at a nominal cost, without the necessity of interrupting the drying
process or sending to the factory for repairs.

G. Location of the contact points of the make-and-break outside the oven and
their enclosure in a tight case, preventing any possibility of the explosion of
inflammable gases generated within the oven.

7. Ease of adjustment of temperature, by means of the thermo-regulator, from

room temperature to the maximum temperature of the oven. This is accom-

plished by turning a removable key outside the oven, actuating a worm gear

which sets the contact points to open or close at the desired temperature.

with five feet of flexible asbestos covered board.

PAPER TESTING APPARATUS

35S5

3586

3385 PAPER TESTER, Mullen type, for testing the strength of paper, fiber-board
and textiles. This instrument accurately and automatically registers the
strength of paper in pounds to the square inch. The paper is clamped
over one end of the cylinder which is filled with liquid. The liquid in
this cylinder is compressed by means of turning a handwheel and the fluid
is forced up against the paper. This fluid pressure is increased until the
paper is burst. At the breaking point the gauge pointer remains sta-
tionary, so the results can be read closely. Pressing on a button releases
the pointer. Besides its use on all kinds of paper, fiber-board and so
forth, the tester is used on such materials as leather, celluloid, textile
goods, etc. The regular size tester is fitted with a gauge to register up
to 160 pounds per square inch, although it is advisable to use lower
reading gauges for such materials as tissue or .newspaper and a higher
reading instrument for. boxboards and textile goods of all sorts.
Paper Tester, Mullen type $100.00

3586 PRESSURE BULKER, Perkins' type. This instrument fills a very definite need
by providing a positive uniform standard for measuring the bulk of paper.
A pile of sheets is placed between the contact faces and the handwheel
clamp is screwed down until the desired pressure is indicated on the
dial. The thickness can be read directly from the vertical scale at the
left. The pressure is indicated in pounds per square inch and the thickness
in inches and fractions of an inch. The present and faulty method is
to caliper one sheet and multiply by the number of sheets in a pile or
package. This plan affords numerous errors, as the thickness of the
paper varies so much that' it is impossible to obtain a representative sheet
Pressure Bulker, Perkins' type On application

We have the facilities for furnishing the latest types of paper and other testing
machines and do not purposely list at this time such instruments which are imported
and which are unobtainable at this period. However, upon the return of normal
conditions, we can furnish any of the imported high grade testing machines.

replacing expensive platinumware, contains less iridium than the regular platin-
umware usually obtained (report of Bur. of Stds., December, 1916), is guaran-
teed to withstand continuously 1,300° C., and has been used by prominent chem-
ists in daily laboratory routine and in varied lines of work, both metallurgical
and industrial.

BARIO crucibles can also be furnished by us. They are guaranteed abso-
lutely resistant to both acid and alkali, and for such ordinary laboratory uten-
sils are equal to platinumware and cost but a small fraction as much.

PUMPS— CENCO-NELSON HIGH VACUUM

These pumps represent the most recent development in High Vacuum Pumps for
laboratory and commercial purposes. They are compact, operate with very small ex-
penditure of power, require no attention when in operation and should last indefinitely.
They measure about seven inches high by five inches in diameter at the base and weigh
approximately ten pounds. The pulley is grooved for %-inch round belt.

Under favorable conditions, a vacuum of 0.1 mm. may be obtained with the Two-
stage Pump. On continuous service, some heating takes place, which lowers the vacuum
somewhat. With the Three-stage Pump, water cooled, a vacuum of .05 mm. may be
obtained by using proper precautions.

The displacement of these pumps in free air, according to tests in our laboratory,
is approximately 285 cu. in. per minute, or 10 cu. ft. per hour, at a speed of 900 r. p. m.

They will evacuate a flask of one liter capacity to a vacuum of 1 mm. in two minutes.

LABORATORY SUPPLIES AND CHEMICALS

The valuable optical properties of quartz crystal, recognized for hundreds of years,
were responsible for the earliest attempts to fuse this material into a homogeneous
glass. Although most entirely without success for many years, these early efforts
revealed the special physical qualities of Quartz Glass, which have since secured for
it such an important position among laboratory apparatus. Its melting point lies
800°C (1400°F.) higher than that of common glass, and it may be subjected without
misgiving to the greatest and most sudden temperature changes. The coefficient of
expansion of Quartz Glass, between 0-1000° C is 0,00000054; i. e., a rod of Quartz
Glass 1 meter long at 0°C expands 0.54 mm. when heated to 1000°C.

Sampler Imbedded in Coal

SAMPLER, "comTeco" Reliable Coal Sampler. Decidedly practical for coal
sampling from cars and piles. Devised so as to sample coal that is 3 inches
or smaller in diameter. The simple construction makes it practical and easy
to operate.

The cut shows the sampler imbedded in the coal. The sample has been
extracted from top to bottom of the coal as it lies in the car. This is the
true way of obtaining a thoroughly representative sample. The pipe thus
surrounds the sample and keeps it intact until it is withdrawn from the
coal. Then, by reversing the spiral, the sample of coal is emptied into a
receptacle suitable for that purpose. The teeth at the bottom of the pipe
act as "grippers," thus keeping the pipe from turning. These, together
with the spiral, act also as a "clipper" and shear off pieces of coal that
wedge between.

"SAFETY FIRST DEVICES"

It is estimated that in this country 60% of accidents are due to negligence
on the part of employers and employees and 40% to the inevitable risks of
employment. It is generally estimated that about 500,000 persons are yearly
killed or incapacitated by industrial accidents, entailing a loss in earning
power of at least $250,000,000 per year. It is necessary, therefore, that atten-
tion be given to prevent such accidents. There are thousands of men in
the industries who are liable to injury and a large percentage of these may
escape injury by equipping themselves with safety devices. If an injury is
received, knowledge and immediate accessibility to first aid appliances will
greatly diminish disabilities and deaths.

Therefore, for those who are engaged in hazardous occupation we are
listing complete lines of helmets, respirators, goggles, asbestos gloves and
suits, rubber gloves, safety first cabinets, and so forth. The articles are
scientifically correct and their plan of use is based upon the highest principles
of humanity.

GOGGLES AND SPECTACLES

workers who are subjected to injury from flying particles or poisonous fumes require
goggles made especially for their particular work.

SPECTROSCOPES AND ACCESSORIES

We are capable of supplying any of the standard American made spectroscopes.
Below we list a type of spectroscope which is in general use in laboratories today.
The smaller instrument is especially adapted for school use. Any apparatus embodying
special optical features can be furnished upon receipt of specifications. Estimates
cheerfully given on any optical instruments, and repair of same.

3810-1

3810-1 SPECTROSCOPE. The usual standard type fitted with collimator,
observing telescope and scale tube. The collimator is stationary and
fitted with adjustable slit having jaws of German silver. The
observing telescope has coarse adjustment only around the axis.
Both collimator and observing telescope are fitted with achromatic
objectives of 25 mm. aperture. The other necessary adjustments
for adjusting the tubes in horizontal position are provided. This
instrument is now furnished with a liquid prism for bi-sulphide of
carbon, but provision is made for adjusting scale tube and observing
telescope so that other prisms of any dispersion may be used. The
cost of the instrument including prism is $48.00

Accessories for this instrument:

1st. Comparison Prism for Slit $ 5.00

2nd. Rack and Pinion Motion for Slit 5.00

3rd. Slow Adjustment for observing telescope (tangent screw) 5.00

4th. Illuminating Burner (gas) for scale tube or collimator 3.00

3810-2 Is a less expensive instrument for school use which is smaller, but other-
wise of the same type as No. 3810-1.

3811 STILL, Stokes' Automatic. By a clever construction this Still accomplishes
several novel results. First, it utilizes the heat generated in the Still
for pre-heating the incoming water to the boiling point and thus a small
quantity will operate the Still after it is once started. Second, by pre-
heating the feed water before it enters the distilling basin, the ammonia
and other gases due to impurities in the raw water, are liberated and escape
into the air through an opening provided for this purpose. Third, the
condenser tubes extend to the extreme top of the steam chamber, high
above the water level, so there is no danger of the raw water being carried
over by the steam. Fourth, the Still can be easily cleaned by opening
the valve connecting- with the drain and flushing, or by removing the lid
on top and scrubbing. The copper steam coil can also be easily discon-
nected for the removal of scale in case the feed water deposits same.

THE IMPROVED "ROCHLITZ" AUTOMATIC WATER STILL

3812

3812(a)

It is well known that the absorptive power of distilled water is second to only
that of acids. All but the precious metals and block tin are susceptible to its action,
and if it comes in contact with tanks, or pipes of other metals, it will be found to con-
tain slight quantities of them in solution. In order to render this contamination
impossible, the "Rochlitz" Automatic Water Stills are lined throughout with purest
block tin.

3812 STILL, Automatic, Gas operated (Rochlitz improved). Simple in construc-
tion. All parts readily accessible for cleaning when desired. Easily oper-
ated and guaranteed to give entire satisfaction. This still is the Rochlitz
Still greatly improved and enlarged, made of copper and brass throughout,
tin lined inside so that the water comes in contact with the tin only. The
outside is nickel plated.

3812(a) STILL, Automatic, Steam operated, "Rochlitz" improved. Attachable to any
boiler, costs but little to install, simple and effective in operation. Pro-
duces Distilled Water at average cost of 1/10 of a cent per gallon.
All impurities are thrown down in the boiling process to the apex of the
conical bottom at which point is located the drain pipe and valve. By
opening this valve at proper intervals, depending upon the character of
the water distilled, all impurities are thoroughly flushed out, keeping the
boiling chamber clean and wholesome.

trode holders, a push button switch to,
short circuit the holders when not in
use, and a switch to change the polarity
of the electrodes. Each lamp on the
upper casting is in parallel with the
electrodes on the center casting in or-
der to take up the current carried by
the solution when the solution is low-
ered, so that the electrodes are out of
contact with it. A motor on center
support revolves the electrodes. The
lower casting carries the beaker sup-
ports.

trodes $200.00 3815(c)

STIRRER, GRAMERCY ELECTRIC

This excellently designed apparatus will be found
useful for a number of purposes besides general
stirring. The motor is fitted with a pulley wheel,
which can be brought to a vertical position by a turn
of the adjustable extension clamp attaching the mo-
tor to the support and allowing the motor to be
raised or lowered, as may be desired.

The removable attachment holding the stirring
rod is provided with a union fitting, which firmly
holds the stirrer and allows it to be quickly and
easily removed. The Universal Motor, 1*5 H. P.,
which can be operated on either D.C. or A.C., is
fully enclosed with an aluminum cover to prevent
dust or particles from getting to the working parts.
It is attached to the support by means of an ad-
justable extension clamp. The heavy iron support,
with base 16 cm. x 25 cm., is fitted with a hollow
upright through which passes the wires from the
rheostat to the motor, which, above the rod, are
sheathed in flexible metallic tubing. A rheostat, hav-
ing ten steps, is neatly fitted under the base of the
support.

3996A SINGLE STRAND TESTERS. Hand operated. In the use of some materials
it is advisable to know the strength of the individual strand. The two
machines shown above are made to be driven by hand. The recording head
is built as a balance wheel rotating upon two large self-aligning ball-
bearings in such a manner as to be extremely sensitive.
No. 3996A. Capacity — 10 pounds by ounces.
No. 3996B. Capacity — 50 pounds by J4 pounds.

3997A. YARN TESTER. Hand operated. This machine is a development of the
old English yarn tester. When a sample has been placed upon the yarn
hooks the hand wheel is rotated until the break occurs. This strain causes
the weight to swing outward away from its vertical position and the pawl
on the lever below the weight holds it in this position until reset by the
operator. Also furnished in power driven types. Capacity up to 250 pounds.

3997B CLOTH TESTER. Hand operated. Produced to satisfy the demand for a

COMBINATION POWER YARN AND CLOTH TESTER

3997C This tester is a combination of the machines listed
on the previous page. The addition of the
automatic recorder has greatly enhanced the
value of the tester. By the use of the recordjer
a chart line indicative of stretch and strength
of the material is automatically recorded. The
chart line shows the exact relation of stretch
to the tensile strength, at every point of the
test. Aeroplane wing fabric and other mate-
rials whose elongatiln under certain tension
is of vital importance can be accurately tested
only by this means.

Can be supplied in sizes of 50 to 600 pounds
capacity depending upon the kind of material
to be examined.

24 grs. (Troy)

109 3-8 grs. or 4 dwts. 13 3-8 grs.

218 3-4 grs. or 9 dwts. 2 3-4 grs.

437 1-2 grs. or 18 dwts. 5 1-2 grs.

7000 grs. (Troy)

= 1 dwt. (Troy).

= 1-4 oz. (avoir'pois).

= 1-2 oz.

= 1 oz.

= 16 ozs. (avoir.) or 1 Ib.

Measurements Used for Cotton Yarns

54 inches = 1 thread or circumference of hank.
4,320 inches = 80 threads = 120 yards — 1 lea.
30,240 inches = 560 threads = 840 yards = 1 .hank.
No. of yards-=-8.33 grains=counts of yarn.
1 bundle usually = 10 Ibs. weight.

Worsted Yarns

In its general features the system of numbering worsted yarns are similar to those
of cotton. The worsted reel is two yards in circumference, and the table of measure is: —
2 yds. = 1 thread.
80 yds. = 40 threads = 1 lea or warp.
560 yds. =280 threads = 7 lea or warp = 1 hank.

12 hanks = 1 doz.
144 hanks — 12 doz. = 1 gross.

THE COUNTS OF YARN is the number of hanks required to weigh 1 Ib. avoirdupois
(or 7,000 grains Troy).

RULE FOR COUNTS — Reel off and weigh a suitable number of leas, add 3 cyphers
to number of leas weighed, and divide by number of grains (Troy) the
yarn weighs; the result gives the counts.

TEXTILE AND YARN INSPECTION

3998A YARN REEL. The reel is 54 inches, or one and a half yards, in circumference. The dial
is graduated into 120 parts, indicating the number of yards reeled from each spin-
dle. The yarn guides and spindles are kept in line with each other while feeding
yarn upon the reel, which is very desirable when reeling fine yarns. The extra length
of yarn guides is of use in increasing the friction upon the yarn by taking a half turn
or more of yarn aroutid them. The automatic feed motion lavs the yarn flat upon
the reel, thus securing accurate and uniform measurement, and consequently correct
results as to stretch, strength and numbering. The bright spot on the web of the
worm wheel is to show when the zero upon the dial approaches the index point, and
thus assists the operator to stop promptly on the striking of the bell. Made in four
or seven spindles.

3998B UMBRELLA REEL. This reel can be furnished with an adjustable clamp base for
attaching to the edge of a table or shelf of any thickness. All parts are of metal and
those coming in contact with the yarn are of solid brass and very smooth. It will
hold skeins up to 72 inches and is invaluable for winding or exa'mining yarns.

3999A 3999B

3999A ROVING OR YARN SCALES. This scale will weigh one pound by tenths of grains, or
one seventy-thousandth part of one pound avoirdupois, rendering it especially well
adapted for use in connection with Yarn Reels, for the numbering of yarn from the
weight of hank, giving the weight in tenths of grains to compare with tables. It is
also useful for the weighing of any small articles, coolrs, drugs, etc., for computation
of large quantities, or for postal scales. The finished parts are nickel-plated and
the stand japanrted and ornamented. Ten balancing weights accompany each scale,
viz.: one each of 20, 30, 60, 100, 200, 300, 500, 1000, 2000 and 3000 grains; the 20
grains on the beambeing each divided into 10 parts. A level glass, to aid in adjust
ment, is set in the base.

3999B YARN INSPECTOR. For comparing and examining fine or coarse, cotton, woolen, silk,
jute or other yarns. The cut shows a machine with inspection board in position.
The yarn is wound from two cops or spools, and is laid evenly in parallel lines upon
boards 17% inches long by 8 inches wide. These boards are held in the machine by
a spring clamp and are instantly interchangeable. Defects of any kind are readily
exposed and samples may be held on file indefinitely for future reference and compari-
son. Twelve boards are furnished with each machine and extra boards will be sup-
plied when desired. The machine is mounted upon a well-finished weathered oak
base and designed with two solid iron side frames which support the mechanism.
All metal parts are finished in black enamel and nickel plate, making this machine
very attractive as well as serviceable.

3999C TWIST COUNTER. This
machine is designed for
ascertaining the number
of twists in yarn. Samples
from one to ten or twenty
inches can be clamped in
the jaws provided for the
purpose and by revolving
the hand wheel until th1?
yarn lays straight and the
strands are parallel, th«>
dial will accurately record
the number of twists un-
raveled.

LABORATORY SUPPLIES AND CHEMICALS

The Thermit reaction is based on the chemical formula Fe2O3+2Al=2Fe-j-Al2O».
In other words, iron oxide mixed with aluminum in approximately volumetric pro-
portions and in the proper state of division will react in such a way that the oxygen
leaves the iron oxide and combines with the metallic aluminum with which it forms
an aluminum oxide or slag, setting free the iron.

The essential characteristic of the process is that when the Themit mixture is
ignited in one spot, the combustion so started continues throughout the entire mass
without supply of heat or power from outside, and produces superheated liquid steel
and superheated liquid slas?. The temperature produced by the reaction attains about
4881° F in less than thirty seconds. The liquid steel produced by the Thermit
reaction represents one-half of the original Thermit by weight and one-third by
volume.

. In order to ignite Thermit, place on top of it a small heap

of special ignition powder. Place on top of the powder a
parlor match, so that the head of it will come about over the
center of the powder, ignite the head of this match by applying
another parlor match. Care must be taken as the reaction
takes place instantaneously.
Welding a Small Boss to a Steel Plate by Igniting the Thermit Directly on the Plate

The materials necessary are
a steel plate, a refractory
pouring cup, the necessary
quantity of Themit (welding
portion No. 1 in can) and
one-half teaspoonful of igni-
tion powder. Place the plate
on some dry sand and put one
of the pouring cups anywhere
on the plate after taking care that the place selected is free from dirt or rust. Then
fill the pouring cup about half full of Thermit and ignite as described above. The
Thermit will burn down rapidly, giving off a bright light. It is advisable to protect
the eyes with dark glasses. When the reaction has been well started, feed in the
balance of the Thermit from the can in a steady stream so as to keep the reaction
going until the entire welding portion has been consumed. About two minutes
after the experiment has been made, tap the pouring cup gently with a hammer so as
to break it up. It will be found that a lump of steel has been welded to the plate.
Materials required: A — 3/16" steel plate. D — 2 pouring cups. J — 2 cans Thermit
and can of powder.

Burning a Hole Through a
Plate

This experiment demon-
strates the intense heat con-
tained in the Thermit steel
and incidentally teaches the
proper manner of closing the
outflow of the crucible (plug-
ging the tap hole) and tap-
ping the same when the re-
action is completed.

VOLUME OF LOAF APPARATUS

Two aluminum receptacles, connected
with a graduated tube, are suitably
mounted on a pedestal and pivoted in
the center for reversing the alternate
ends. A funnel orifice in the center
of the tubing causes the seed to
flow uniformly from the top to the
bottom receptacle like an hour-glass.
This mechanical filling of the lower
receptacle insures the same degree of
compactness under all conditions,
therefore, machine accuracy. To
operate the measure, the lid of the
top receptacle is removed, mustard
seed is poured in until the standard
quantity is registered. The loaf is
secured to the top lid by a spring
clamp; the lid is then replaced and
the position of the two receptacles
reversed; the seed flowing through
the orifice in the center of the tubing
fills in around the loaf in the bottom
receptacle. The amount of seed dis-
placed registers the volume of the
loaf on the tubing, graduated in
cubic centimeters. The operation is
repeated \v;lh additional loaves, using
the alternate receptacles. The recep-
tacles are made to accommodate the
regular commercial pound loaf.

TEST TUBE OR BOTTLE WASHER

4233

The above illustration shows the Washer made with 24 Washing Tubes. Twelve
8" and twelve 12". Dimensions over all 14"xl7". Two Control Cocks.

This Washer, designed for the Johns Hopkins Hospital, enables one to rapidly
Cleanse Test Tubes of all lengths, the longer Tubes being suitable for washing any
tube up to 14" long, as the water when turned into the High Tube section by turning
off the low service will spout six or more inches in the air. The whole 24 Tubes can
be used where there are only short tubes to be washed and if the head of water
has sufficient pressure.

The waste water will run off the Washer into the sink at the vent shown at the
opposite end from the Control Cocks.

Hot or cold water can be used as desired. The inlet is at opposite end from
the Control Cocks, and we furnish ample length Heavy Rubber Hose to connect
to the usual water supply.
Price $45.00

We are listing the above test tube washer, which we consider is an essential in
a laboratory of any size. This washer is also adapted for washing such articles as
Babcock Milk and Cream Testing Bottles. The apparatus washes both short and
long tubes. Also furnished for tubes of 6, 8, 10 and 12" lengths, with a control cock
for each size of tube. Prices for types other than the one herein listed upon request.

TEST TUBE BOILER AND STERILIZER

A most unique and practical addition
to the laboratory.

It consists of a small cylindrical

^jjjnjrjjjfr . drum, having a nickel-plated metal body

with a top and bottom of J4-inch trans-
ite. The dimensions of this drum are:
height, 2l/4 inches; diameter, 3l/2 inches.
The apparatus is mounted upon three
leg's.

Located near the center of the drum
there is a metal cup or cylinder 1 1/16
inches in diameter and \l/2 inches in
depth. This is the heating receptacle.
The cup is encased in a resistance
coil, which provides equal distribution
of heat to the entire surface of the
receptacle simultaneously, heating it
uniformly and very quickly.

This resistance coil or heating unit
is controlled by an automatic-electro
thermo-regtilator, contained within the
drum. It is adjusted by means of a
small screw. To reach the adjusting
screw of the thermostat it is necessary
to use a small screwdriver. This pre-
vents tampering.

The thermo-regulator completely con-
trols the temperature so that the con-
tents of the test tube may be brought
to the boiling point without boiling
over. Metal rings are provided for the
receptacle, permitting the use of the
following sizes of test tubes: Yz inch,
•Hs inch, y± inch, and 1 inch.
Price, complete, including test
tube and small crucible, as per
4235 illustration $10.00

These indicators are manufactured in a spirit of co-operation with medical research,
rather than for profit. It is desirable, therefore, to distribute them in quantities of not
more than five decigrams to a large number of investigators. In special instances, larger
quantities may be obtained, should they be actually needed, and in the future, if large
quantities of the indicators are required, the demand will be met.

BACTERIOLOGICAL AND MICROSCOPICAL APPARATUS

5000

5000 AUTOCLAV OR DIGESTER, "Eclipse" Patented, Made of extra heavy copper
and brass throughout, no iron or other metal to rust or corrode. The
ingenious construction of the door, which is of cast brass and is convexed
to maintain perfect symmetry of the body. When opened, it fits snugly
the inside body of this sterilizer, leaving the entrance and interior en-
tirely clear.

The door and head are perfectly ground and fitted, requiring no packing
or gaskets, which are always a source of considerable annoyance and
expense. The Eclipse sterilizers have no locks or spring on the door. No
device to get out of order.

They may be opened or closed instantly without effort.

It is impossible to open the door while there is the slighest pressure in
the interior, and there is never any danger of scalding. We emphasize
this statement as numerous accidents have occurred with faulty mechan-
ical arrangements on sterilizer doors or leaky gaskets.

The steam fills the outer jacket and enters the inner chamber at once.
This operation prevents the contents from becoming moist by the con-
densed steam.

Can be used as a free steam, non-pressure sterilizer by opening the air
cock if desired. Mounted on white enameled stand. Heated by Steam,
Gas, Gasoline or Petroleum.

LABORATORY CAGES

We furnish bacteriological laboratories with all types of cages. They are con-
structed of various materials depending upon the use to which the cage is to be
put. These cages, of which only a few are listed, are used for breeding purposes
and for the close observation of animals used as subjects in innoculations and so
forth. Each cage is designed to fit the particular animal under study, as the cat,
dog and rodent. All cages are made so that they may be easily and quickly cleaned,
and many are collapsible for storage and convenience in sterilizing. We shall be
pleased to furnish detailed description and prices of any type not listed below.
Any special type involving new ideas can be furnished by us with price upon appli-
cation.

with Bureau of Standard certificate for both counting chamber and
pipettes 24.00

The Levy Counting Chambers possess the following distinct characteristics:

Increased visibility of the rulings when chamber is filled with solution.
The new method of construction entirely avoids the cemented cell and the
attendant danger of its looseniqg by the drying out of the balsam cement,
and the possibility of the loosening of the ruled counting surface is also
greatly reduced by this construction.

The parallel form of cell first suggested by Biirker and used in all Levy
counting chambers provides a more uniform distribution of corpuscles over
the ruled area and entirely removes the effect of atmospheric pressure
upon the depth of the solution, a souce of considerable error in the
circular form chambers.

DOUBLE COUNTING CHAMBERS— We especially recommend the use of
the double chamber, in which the rectangular strip in the center of the cell is divided
by parallel moats and each half provided with a Neubauer ruling, so that both red and
white counts may be made at the same time without the necessity of cleaning and
refilling the counting chamber. This double type of counting chamber has been for
several years used in, and recommended by, the clinical laboratories of the Johns
Hopkins Medical School and has been recently purchased in large quantities by the
U. S. Army Medical Department, and is rapidly coming into wide use because of its
convenience.

ELECTRIC INCUBATORS WITH DRAWER COMPARTMENTS

The Compartment Incubator is manufactured in three sizes to contain either 24,
36 or 48 drawers.

The idea is to furnish a separate drawer or compartment for the individual use
of each student.

Inside dimensions of each compartment: Height, 6 inches; width, 5 inches; depth,
18 inches.

The Incubators are heated with lamps provided with steel chimneys for protection,
or, if preferred, electric heating units with pilot lamps. Controlled by our latest
automatic electro-thermostats.

The drawers rest upon steel frames and the entire Incubator is lined inside with
animal hair and transite for perfect insulation t and to guard against fire.

These drawers are made of perforated galvanized steel so as to permit the heated
air currents to circulate freely through all the compartments.

Proper ventilation and air circulation have required much careful investigation.
These questions had to be settled by actual test, to the end that each and every com-
partment might retain its proper degree of temperature relatively.

The cabinets are mounted on angle iron stands to raise them to a convenient height
from the floor.

It is the ideal Incubator for Universities, Colleges, Schools or wherever cultures
are made.

8134 Combined Electric Incubator and Paraffin Oven. The above illustration repre-
sent an apparatus both unique and practical in Electrical Laboratory
Equipment.

The size and construction is the same as in our No. 6133 Electric In-
cubator, except that a dividing partition has been added, which separates
the compartment into two chambers of equal size of the following dimen-
sions: Height, 30 inches; width, 17^ inches, depth, 18 inches.

The partition is made of cork 1 inch thick, protected on each side with
a layer of transite; the whole being 1% inches thick.

This construction insures perfect insulation between the two chambers,
to the end that both may be used simultaneously — one for incubation and
the other for paraffin work.

Each chamber is supplied with its own heating units, pilot lamp and
Electro-Thermostat, thus permitting the use of either chamber irrespective
of the other.

The Paraffin Oven contains Paraffin Receptacle (see description),
which is provided with five shelves, each having nine holes 2tV inches in
diameter for paraffin dishes, thus affording large capacity for work.

This Combination Incubator and Paraffin Oven not only represents
economy of space, but also obviates the necessity of having two separate
pieces of laboratory apparatus. It is supplied with an angle iron stand 32
inches high and with thermometer for each compartment.

6136 ELECTRIC INCUBATOR, for Maintaining the Entire Microscope at a Constant

Temperature. For those desiring to make a special study of Micro-organ-
isms at blood temperature for any length of time, we have constructed a
special Incubator, in which the entire microscope may be placed. Both
sides arc provided with hand holes, which enable the operator to manipu-
late the microscope in the ordinary way. When not in use the hand holes
are closed by metal slides.

The Incubator is made of insulating material and has a removable
plate glass front. A Bausch & Lomb B B H miscroscope, which is shown
outlined in the cut, requires an Incubator 7 inches x 7^ inches x 9 inches
deep inside dimensions.

Where the size of the microscope is similar to above, no extra charge
will be made, but should the size of the microscope necessitate a consider-
able change, such alterations will be charged for accordingly.

. This Incubator is particularly well adapted for universities and research
laboratories. It is used to advantage in watching developments of Em-
bryos of animal parasites and also in watching the growths of normal and
abnormal tissues. It is convenient in bacteriological and zoological research
work and in research work on blood. An apparatus like this opens up
many new lines of research.

6138 ELECTRIC INCUBATOR, for the Microscope Stage. This warming stage is a
miniature Incubator complete in itself. It fits the mechanical stage of any
standard microscope.

The outside dimensions are 3^ inches x 2 inches x Yz inch in thick-
ness. The incubating chamber measures 3 inches x 1 inch x Yz inch in
depth and has a removable glass bottom consisting of a regular 3x1 slide.
The specimen to be examined is placed on this slide. The condenser may
thus be brought up close to the glass, same as under ordinary conditions,
permitting the use of the oil immersion lens.

\

To cover top of Incubator we furnish a piece of clear Mica having a
hole cut in center through which the lens is passed when making adjust-
ment for the bottom, slide. A rubber washer slipped over the lens is pro-
vided for sealing the opening between the lens and mica. (See illustration.)
By this arrangement a perfect incubating chamber is obtained where
bacteria may be observed for any length of time.

The Incubator is complete in every detail with heating element, ther-
mometer and adjustable electro-thermostat, which automatically main-
tains a constant temperature inside the incubating chamber, as long as the
electric current is on. This device can be adjusted for any temperature
between 80 and 110 degrees Fahrenheit and is very accurate.

To operate, simply screw the current tap with its lamp into any 110-
volt electric lamp socket and turn on the current.

Incubator answers all the requirements that a warming stage should
have. In the Widal test for typhoid it may be used to great advantage. It
is particularly well adapted for observation of Plant micro-organisms,
such as bacteria and yeasts in a hanging drop, or a hanging Agar block;
also for observation of Microscopic animal-organisms such as Malarial
Parasites, Trypanosomes and Amoeba.

A number of diseases found in all tropical countries cannot be properly
examined without a Warm Stage.

For cultivation of Spirochetes and tumor cells by the recent methods
of Harrison, Noguchi and others, this apparatus has no equal.

6140 Electrically Heated "Warm Stage" for the Microscope. Our electrically heated
"Warm Stage" is the only appliance of its kind now on the market. It will
be found most compact and convenient and always ready for use, as it fits
the stage of any microscope without adjustment.

To operate, simply screw the current tap with its lamp into any 110-
volt electric lamp socket and turn on the current.

The Warm Stage measures 8^2 inches in diameter x J/2 inches in thick-
ness and has a 54-inch hole in the center over which the regular micro-
scopic glass slide may be placed.

It is complete in every detail with heating element, thermometer and
adjustable electro-thermostat that automatically maintains a constant tem-
perature on the top of the disc, as long as the electric current is turned on.
With this Warm Stage, micro-organisms requiring blood heat temperature
(98° Fahrenheit) for maintaining their motility, can be readily discovered
and examined.

The most important purposes for which the Warm Stage may be used,
among others, are as follows:

a. To determine if a case of dysentery is of amoebic variety, Entamoeba
Dystenteriae (Histolytica). The stools or scrapings from the rectum
are searched on the Warm Stage for living moving Amoeba.

b. To search for Plasmodium, Plasmodium Malarae, in the fresh prepara-
tion of patient's blood in the diagnosis of suspected Malaria.

c. To ascertain if the fresh Spermatozoa is alive. This is of particular
value in the Medico-legal cases.

d. To discover the presence of Amoeba, Entamoeba Buccalis, in suspected
cases of Pyorrhea Alveolaris.

When it is desired to examine a large area the Warm Stage is most
practical. This device is intended to supplant the old, cumbersome hot
water warm stage. It is light, compact and convenient. It relieves the
operator of all worry as to its positive efficiency.

The illustration shows the application of the "Warm Stage" to the
microscope .^ table.

6142 THELCO LOW TEMPERATURE INCUBATOR. Constant temperature in the
Thelco Incubator is maintained by circulation of cool air around the nar-
row water jacket of the incubator chamber. The cool air is admitted from
the ice chamber through a shutter operated by a milled head screw on the
outside. This shutter is adjusted to maintain a cool air temperature slightly
below that required and the electric heating plate under the water jacket
brings the chamber to the right temperature. A Thelco spiral bimetallic
regulator controls the heating plate. This method maintains a uniform
temperature throughout the chamber and is very economical of ice. In
ordinary weather a single supply of ice will last several days. Although
designed primarily for gelatine culture cultivatipns at 20° C, the incubator
can be used just as satisfactorily at any predetermined temperature from,
about 10° C. to 40" C, or at temperatures below 10° C. by using a suitable
cooling mixture.

The heating plate is a wire-wound resistance, readily removable and
controlled by the strong but sensitive Thelco regulator, which maintains
the temperature constant to 1° C. A switch for turning on and off the
current and a pilot lamp are mounted on top of the apparatus.

The incubator chamber is double-walled, of heavy copper and pro-
vided with three perforated shelves, which may be placed at any desired
height. It has a felt-cushioned, glass door, which is air-tight. The cabinet
is of wood, insulated with felt and dead air-spaces, making in all 10 walls.
It is entirely sheathed in steel plate, handsomely finished in white
porcelain, with polished aluminum trimmings. The incubator is mounted
on a heavy iron base. Size, 46 inches high, 38 inches wide, 31 inches
deep $325.00

6186 MICROSCOPE — Spencer^ Lens Co. No. 64. This microscope has proven a
standard of its own. It is exceedingly desirable for general biology and is
in daily use in hundreds of laboratories.

The Body Tube is our standard, 37 m.m. in diameter, taking standard
objectives and oculars.

The Arm and its Side Fine Adjustment "D" are identical with Micro-
scope No. 44. This adjustment is patented, is exceedingly durable, will with-
stand very hard usage and not develop lost motion. (See description and
diagram illustration under No. 44.) It travels laterally, giving an instant
visible index of the position of the adjustment relative to the total excur-
sion. Steel pins in heads of buttons produce an absolute stop at either
end of excursion, preventing jamming or binding of screw. There are
but two bearing surfaces and three working parts. The main bearing is
made of one single piece. One revolution moves the tube .2 mm. Ad-
justment ceases to work when objective comes in contact with slide.

The .Stage, 112x108 mm., is completely covered with vulcanite rubber,
vulcanized directly to the stage plate. Beneath the stage is an iris dia-
phragm operated by a knurled wheel, 62 mm. in diameter. Abbe Con-
denser is supplied when ordered, and is fitted in a simple, spiral focusing
substage ring. Distance is 80 mm. from optical center to arm.
Furnished in hardwood cabinet, lock and key.

6188 MICROSCOPE, Spencer Lens Co., No. 44-H. This instrument has pnoven the
most popular of all Spencer Microscopes. Many hundred are in daily
use, in medical and general laboratories, also by physicians. This, we
believe, is the best microscope value on the market.

The Body Tube is standard, taking standard objectives and oculars.

The Arm is strong and very graceful, fitted with Side-Fine Adjustment
and possessing many exclusive features. It has but two bearing surfaces
and three working parts. The patented one-piece construction bearing
carries the solid steel screw. This screw, with no less than twenty threads
engaged even at the limit of its motion, has a heavy flange, F, working
against the level, L. When the screw is turned in snch a direction as to
carry F forward, the lever is so swung as to raise the body tube. The
reverse motion permits the tube to be lowered under the influence of
the spring, The focusing buttons at either end of this screw travel
laterally and serve as a visible index of the center of the fine adjustment
action. Steel pins in the heads form positive stops at either end of
the excursion. The direction in focusing is the same with both fine
and coarse adjustments. One revolution moves tube .2 mm.

The Stage, 112x108 mm., is completely covered with genuine vulcanite
rubber, vulcanized directly to the stage plate. Distance is 80 mm. from
optical axis to arm.

The Substage is standard quick-screw form.
Furnished in hardwood cabinet, lock and key.

Equipped with Huyghenian Oculars 6x and lOx, objectives 16 mm. (2/3"),
4 mm. (1/6"), dry, and 1.8 mm. (1/14") immersion, triple nosepiece, quick-
screw substage, Abbe Condenser N. A. 1.20 with iris diaphragm. Com-

6190 MICROSCOPE, Spencer Lens Co. No. 15

This microscope is a very high grade instrument.

The Body Tube is standard size, taking standard objectives and oculars.

The Arm is large enough to comfortably grasp same with the whole hand.
It is fitted with Fine Adjustment "B," which is very durable, automatically
taking up wear. There is no lost motion. The button is graduated
with 100 divisions, giving a reading of single microns. One revolution
moves the body tube .1 mm.

The Revolving Stage, 120 mm. diameter, is covered with vulcanite and
centered by means of centering screws. The distance from optical center
to arm is 90 mm. This stage with —

The Mechanical Stage is in reality two stages in one. The lateral move-
ment is 60 mm. and the to-and-fro excursion, 38 mm.

6194 MECHANICAL STAGE, Spencer Lens Co. The most popular mechanical
stage yet produced; attachable to any modern square staged microscope.

A stop at the front always insures its return to the same position on the
microscope stage. Should work be interrupted and the mechanical stage
be removed, when replaced, the object of interest may readily be found,
providing the vernier readings have been noted. The vernier of the lateral
movement is placed slightly to one side of the arm of the microscope where
it may easily be read.

The movements are by diagonal rack and pinion, and are firm and reliable,
permitting the most delicate adjustments. The range of movement is
ample to cover the entire area of the standard slide, 1x3 inches.
Finished in alcohol-proof black enamel, complete in cabinet $19.00

maroon-colored japan with bronze stripes. The inside finish is in black
japan. It contains thirty japanned metal trays, each holding twenty-four
glass slides, 75x25 mm. The trays are provided with convenient knobs and
with card holders. The new, improved construction of the trays holds each
slide independently in its place, preventing shaking or slipping of slides
when trays are removed The cabinet is furnished with a good brass lock,

6334 MICROTOME, Ether Freezing Attachment, Spencer Lens Co. This freez-
ing attachment consists of a freezing chamber of hard rubber which so
prevents the radiation of the cold that the tissue is quickly frozen.
It will freeze tissue, 15 mm. in diameter and 3 mm. thick, in one
minute, using only 5 cc. of ether.

The ether is held in the metal tank, which for filling may be unscrewed
from the support from which it is suspended. Any excess of ether
which does not evaporate is drained back into the metal chamber
from which it came. There are no bottles or entangling tubes and
no waste of ether. It is simple, compact and efficient. It can be
used on any sliding microtome $7.50

6336 MICROTOME Freezing Attachment, for use with Carbonic Acid.

The superior qualities of this freezing chamber have been well recog-
nized during the past ten years. It is substantially made, easy to operate
and eminently efficient. There is a hard rubber non-conducting ring (the
suggestion of Dr. L. D. Wilson of St. Mary's Hospital, Rochester, Minn.)
between the corrugated plate to which the object is frozen and the rest
of the apparatus. This prevents the conduction of the cold from the speci-
men to the other parts, thus saving time and gas.

6343 MICROTOME — Spencer Lens Co., No. 820. The Spencer Rotary Microtome is
an original construction. It is intended for the most accurate and careful
work. An inclined plane feed, which is independent of the up-and-do.wn
movement on the perpendicular support, overcomes the inaccuracies inher-
ent in other rotary microtomes. The most important element in a micro-
tome is an accurate and reliable feed mechanism. This, and rigidity, are
vital. These points are paramount in this instrument.

The feed is so arranged that it can be set for sections of any thickness,
from 1 micron to 60 microns, by turning the knurled button at the back
of the case until the number representing the desired thickness appears
opposite the indicator at the small opening in the side of the case near the
balance wheel.

The total excursion of the feed is 37 mm., allowing a sufficient range
for cutting a complete series of a very large object without the necessity
of a break due to resetting the knife and feed mechanism.

The object clamp is a part of a ball which fits into its socket so
uniquely that it is clamped as solidly as though it and its socket were one
piece. The object is easily, accurately and delicately oriented to any de-
sired angle. The angle can be changed in any plane without interfering
with any angle already attained in another plane. The object may easily
be rotated.

The up-and-down stroke of the object clamp is 50 mm., which permits
the cutting of very large sections and gives sufficient stroke for celloidin
cutting.

The knife is fastened by two clamps, each of which clamps the knife
at the back and along \Y$ inches of the edge as well. It may be turned to
any desired angle, and the clamps may also be moved toward one another
to bring them as near to the ribbon as desired to gain additional rigidity.
When the clamps are thus drawn together, the knife may be moved so that
practically all of the cutting edge can be used before the necessity of
resharpening. The adjusting screws provide for knives of different widths.
The balance wheel is grooved, so that the instrument may be run by a
motor.

6418 SLIDE WARMER, Electric, to provide a convenient method of mounting
paraffin sections. The slides are heated slowly and evenly over their
entire extent to a temperature just below the melting point of the
paraffin, thereby giving maximum flattening without damage to the
specimen. Forty slides can be accommodated at one time. A ther-
mometer is placed just below the block of transite and registers a
temperature somewhat lower than that on the surface. With paraffin
of 55° the best results are obtained when the regulator is set to main-
tain a thermometer 'temperature of 43°. The slides are protected
from dust while drying by a metal hood which is placed over the
apparatus. With this slide warmer drying is cut down from 24 hours
at room temperature to 2 or 3 hours at a temperature just under the
paraffin melting point. Price, complete.. $35.00

6422 ELECTRIC STERILIZERS or Drying Ovens. The frame work of our
Sterilizers are made of steel, with bodies of transite and fittings of
lacquered brass. Electric Sterilizer is made with double walls of
transite, with an intervening dead air space and is furnished with
double doors, thus insuring perfect insulation. It is constructed to
maintain temperatures of from 60 to 200 degrees Centigrade, with a
maximum current consumption of approximately nine amperes.

The inside dimensions are: Height, 10 inches; width, 18 inches;
/ depth, 10 inches. It has two removable shelves and will, therefore,

accommodate glass apparatus of various sizes.

The Heating Medium consists of six self-contained wire units,
which are wound on natural lava stones, thus preventing crumbling
and disintegration, with greatly increased stability of the unit. The
units can be easily removed with the aid of a screwdriver and re-
placed with new ones, should they burn out. A pilot lamp is pro-
vided to indicate when the current is on or off.

The heating units are governed by a controller and thermo-regu
lator, the operating screws of which are located on the side of the
Sterilizer near the bottom. These afford means of utilizing two or
more of the units at a time, as occasion may require. The elec-
trical connections are complete, including special six-foot cord, with
snap switch, ready for instant connection. Chemical thermometer
included.

Owing to the amount of current (9 amperes) required to operate
this Sterilizer at its maximum heat, special provision must be made
for an electric circuit other than the ordinary light circuit. Weight,
packed for shipment, 85 pounds. Price, complete as per cut $110.00

LABORATORY TABLE

The Laboratory necessitates the use of
an assortment of various apparatus, chemi-
cals, glassware, etc., that always take up
valuable space and usually consume time in
assembling, whenever a test is to be made.

To facilitate the work in the Laboratory,
we have designed a compact Laboratory
Table, with a place for everything, thus
eliminating time usually spent in looking
for things, or in connecting or disconnect-
ing electrical apparatus, that are being used.

General Description.

The Cabinet is made horn selected quar-
ter-sawed oak, with a massive and substan-
tial construction. It is finished in light oak
with the finest high grade hand-rubbed fin-
ish. The top of the working table is fin-
ished in the customary acid-proof black.
The dimensions over all are: height 56",
width 56", depth 33". Size of working
space, 5524"xl8". Height from floor 30".
The upper part of the cabinet is divided
into two equal compartments, each 20^4"
high x 25l/z" wide x 31J4" deep and provided
with two adjustable shelves. Specially
constructed roller curtains, easily closed or
A hole 3" in diameter is provided in the

right hand corner of the second compartment, permitting the convenient disposal of
refuse into a jar. placed on a small shelf in the compartment belo^. The lower
part of the cabinet has two compartments, each 25" high x 15" wide x 30" deep,
equipped with doors. The right hand compartment is provided with an exceptionally
solid, stationary shelf intended to support a Centrifuge. The space below this shelf
as well as the left hand side compartment are jntended for storage purposes of
glassware, etc. There are two drawers, each 2^2" high x 8^" wide x 2124" deep.
One of them is divided into several small compartments while the other one is
without divisions. All compartments and drawers are furnished with locks and keys,
thus preventing tampering.

ATTACHMENTS AND ACCESSORIES

A porcelain sink, 7 inches in diameter by 6J^ inches deep, is furnished together
wtih a gooseneck faucet. Water and gas connections are provided and arranged so
that every convenience is offered the operator.

Size of water connection y% inch

Size of gas connection $£ inch

Size of drain i inch

A Burette Holder is also furnished. This holder is attached to the side of the
dividing partition in the upper part of the Cabinet. It may be removed, when not
in use, so as not to interfere with the closing of the roller curtain. The Burette
is held in position by an easily adjusted spring, permitting adjustment both hori-
zontally and vertically.

Electrical Connections. The table is wired for electricity. A push switch, located
on the right hand side, cuts off the electric current to the entire table. Four Edison
Base Sockets installed conveniently at the right hand corner of the working space,
afford connections for the electrical apparatus required. A special socket in the lower
right hand compartment provides connection for a centrifuge.

An adjustable Desk Light is installed at the top of the Cabinet, directly over the
dividing partition. This light is provided with a separate switch.

In the center of the table, in a position most appropriate for the use of a micro-
scope, there is embedded an electric microscope lamp, covered with approved daylight
glass. A convenient push switch is provided for this lamp. When not in use the
daylight glass is protected by a hinged metal cover, which folds down flush with the top
of the table.

An electric cord wtih attachment plug is also furnished and the table may be
attached to any electric light socket without danger of burning out the fuse.

MANUAL

In order to enable the physician to more accurately perform the laboratory tests,
essential to clinical diagnosis, we furnish a complete working manual with each table.

6456 Muencke's Improved Thermo-Regulator for low pressure only. In this
regulator a stopcock controls the passage of gas through the horizontal
tube to the reserve flame. When the temperature rises the gas supply
is reduced by the mercury closing the passage at the fork » $7.50

6458 Reichert's Thermo-Regulator, improved form with stopcocks to prevent

extinguishing the flame 5.00

6460 Dunham's Thermo-Regulator. This is an extremely sensitive regulator in
which the sensitiveness is derived from a large alcohol bulb. The
minute changes in the volume of the alcohol as caused by the varia-
tions in temperature act upon a U-shaped column of mercury and
control the volume of gas which passes through" the tubes Adjust-
ments for the different temperatures to be maintained are made by
sliding the gas inlet tube upward or downward as required. The
thermostat is furnished complete with liquid and mercury for rilling.
A set of directions for use is supplied with each instrument 5.00

or low temperatures and the regulator may be adjusted so that the
maximum flow of gas, which is ample for high temperatures, may be
reduced to an amount just sufficient to keep the flame from going out.
When used in connection with the gas pressure regulator, Merrill's, it
will be found to work to the greatest satisfaction $10.00

6466 THERMOSTAT, Pencil Type. The Thermostat shown herewith is used for
controlling temperatures of liquids. It consists of a thin copper tube
hermetically closed at the bottom end, so that it may be partly immersed
in liquids without damage to the interior. A sensitive bimetallic bar
extends from the bottom half way up the tube

The range of the Thermostat is from 30 to 80 degrees Centigrade.
A special condenser is mounted inside the tube. The .condenser kills
the electric spark when the contact points are separated, thus protecting
same against destruction, provided the electric current does not exceed
1 ampere.

The dimensions of the Thermostat are: 6 inches in length x 54-inch in
diameter.

Price, complete. $12.00

6468 Combination Electric Heater and Pencil Type Thermostat for Heating and Con-
trolling Temperature of Liquids in Water Baths.

The apparatus consists of a heating disc, measuring five inches in diam-
eter by one-half inch in thickness and an adjustable pencil type electro-
themostat, measuring six inches in length by five-eighths of an inch in
diameter, together with a pilot lamp indicating when the current is on
or off.

They are mounted together and are self-contained, with a six-foot cord
and attachment plug, which may be connected to any 110-volt electric light
socket.

Constant water level in the bath is desirable for best results; water bath
heater provides for the maintenance of any temperature between 35 de-
grees and 60 degrees Centigrade in any suitable utensil. It is not necessary
to use a water bath as shown in the illustration. The apparatus can be
applied to any water bath where the maximum capacity of water does
not exceed two quarts.

ARMY MEDICAL SCHOOL MODEL WASSERMAN BATH

6374

DESCRIPTION

This Pattern Wasserman Bath which has been adopted as the Standard for the
United States Army, is most economical in operation.

The Water Vessel which measures 30"x23"xl2" deep, on the standard size, per-
mits the use of a very large volume of water. Being surrounded by a Case of
Polished Rust Resisting Iron, lined with a heavy layer of asbestos, the water holds
its temperature with the minimum expenditure of heat. A single Micro burner being
sufficient for this large bath when gas is used.

The only part exposed to the air is the lid.

The Lid is made double the outer, or top being flat, the inner lid sloping to rear.
The condensation which forms on the outer lid falls on the inner lid, flowing to
the two rear corners prevents any dripping of water into the Tubes from injuring
the specimens being tested.

There is furnished with each bath a Thermometer, also a Gas Thermo Regulator
and two Micro Burners.

The Constant Level which maintains the correct height of water in the bath is
very simple, and easily connected with two rubber hose, one from the water supply
and the other to the waste pipe. The use of this feature is optional. The amount of
water evaporated being very little.

When Electric Equipment is ordered with this, we furnish an Electro Regulator
of the best make and all necessary connections, Lamp Switch, etc., to use on either
110 or 220 volts.

The racks furnished, 20 in number, are marked from 1 to 200, are the Standard
Army Medical School Wasserman Type.

WASSERMAN BATH

This Bath designed for
Doctor S. R. Miller of the

Phipps Psychiatric Clinic of
Johns Hopkins Hospital of
Baltimore, Md.

Being mounted in an As-
bestos lined Russian Iron
Stand, maintains the re-
quired temperature 37^"
with the smallest possible
consumption of gas.

The Water Pan and the
Lid made of Heavy Copper,
heavily coated on the inside
with pure block tin and pol-
ished outside, having a spe-
cially constructed Double
Lid the inner one of which
slopes toward the rear, pre-
venting any dropping of the
Condensation of the Sera
being tested.

The Thermometer Holder
is so arranged that the Ther-
mometer maintains its up-
right position at all times,
thus when necessary to place
near a wall, the Thermome-
ter does not have to be re-
moved when raising the lid.

There are two other tabla-
ture openings provided for
such times as they may be
desirable.

Manufacturers of

"America's Standard"

Evaporator

Largest double effect in use today for hide glue liquor. Standard Swenson horizontal tube
type. Over 80 per cent of the glue made in the U. S. A. is concentrated in this type evap-
orator which turns out the strongest and lightest colored glue.

Single and multiple effects for handling any
liquor in commercial quantities. Sizes reg-
ularly range from 100 to 10,000 gallons of
evaporation per hour. We manufacture five

standard types, although when these do not meet
the requirements we construct combinations of these
types or special types to produce the desired results.
We frequently find it necessary to employ some
special material of construction such as aluminum
or bronze or tile or lead.

Specialists

Swenson engineers are specialists in evaporation and
all reclaiming machinery — which includes vacuum
pans, leaching batteries, beet sugar machinery, pulp
mill machinery, special chemical and waste product
machinery.

Catalogue

The Swenson catalogue containing evaporation data
and tables will be mailed gratis to responsible parties
showing their business or collegiate connection,

Your attention is further directed to the information on
Swenson Evaporatoi s on Page 134.
