Saybolt
Viscometer
The Saybolt Viscometer is used to test the viscosity of various petroleum
products. The interior of the bath is constructed of steel and the exterior
is of polished stainless steel. Three open wire heater coils provide
heating over the full temperature range. A copper cooling coil can also
be acitvated. The temperature can be controlled by a mercury-type thermoregulator
with fine adjustments. An externally mounted induction motor drives a
stainless steel stirrer for thorough oil circulation. Draft shields are
provided to prevent drafts from affecting oil thread. A control box mounted
to the bath is equipped with (2) pilot lights, switches and line terminals.
Also includes corks with pull chains for tubes, tube cleaner, thermometer
guard pipette, and oil strainer. Three gallons of special oil, plug and
cord also included. Applicable Standards: ASTM D 88, D 177, D 244, AASHTO

Asphalt
Institute Vacuum Viscometer
This Viscometer is used in determining the absolute viscosity of highly
viscous materials such as asphalt cement. It measures viscosity ranging
from 42 to 200,000 poise. Includes a graduated capillary. Sample size of
3 ml and bath depth of 7 in. required. Includes rubber holder for 2 in.
diameter hole. Applicable Standards: ASTM D 2171 AASHTO T 202 |

Kinematic Asphalt Viscosity Test Set
This test set is used in determining the Kinematic Viscosity of cut-back
asphalts and road oils at 1400F and asphalt cements at 2750F ranging
from 0 to 6000 centistokes. Applicable Standards: ASTM D 2170 AASHTO
T 201 |

Pressure
Regulator
The Pressure Regulator is used for accurate, precise measurement and control
of pressure from 500 mm Hg below to 500 mm Hg above atmospheric pressure.
Designed for use with vacuum viscometers but may be used for a wide variety
of laboratory applications. Connected to vacuum source and vacuum manifold
by tubing. 2-1/2 lb of mercury is required for use, and must be purchased
separately. |

Zeitfuchs
Cross-Arm Viscometer Set
A complete set of Zeitfuchs Cross-Arm Viscometers for use in measuring
kinematic viscosity of cut-back asphalts, road oils and asphalt cements.
Includes round metal holder (to fit 2 in. diameter hole) for each viscometer.
Includes one of each Zeitfuchs Cross Arm Viscometers (7 total). Applicable
Standards: ASTM D 2170 AASHTO T 201 |

High-Temperature
Viscometer Bath
The High Temperature Viscometer Bath is used for temperature control of
the viscometer when testing asphalt samples over a temperature range from
680 to 4000F maintaining ±0.01F0. Utilizes 3 thermoregulators with different
temperature ranges for greater sensitivity. Mounted stirrer motor is surrounded
by a cooling coil for low temperature tests. The Bath accommodates up to
7 viscometers in 2 in. diameter holes and has a removeable front lid for
accommodation of larger items. Front lighted for easy viewing of viscometers
and well insulated and sealed for safety. Bath made of Pyrex glass with
a stainless steel reflector, heaters, baffle, stirrer, cooling unit and
control panel. Includes 6 gallons of heating oil. Thermometers and viscometers
sold separately. Applicable Standards: ASTM D 2170, D 2171 AASHTO T 201,

Hubbard Specific Gravity Bottle For Oils & Tars
This Hubbard Specific Gravity Bottle is especially made for testing road
oils and tars, asphalt cements, soft tar pitches, drying oils, varnishes,
resins and insulating varnishes. Ground, glass stopper has 1/16 in. (1.6
mm) opening. Applicable Standards: ASTM D 70, D 1963, D 115 AASHTO T

Constant
Temperature Viscometer Baths
These baths are designed for viscosity determinations with glass capilliary
viscometers.
Model A-380 has a temperature range of 200 C to 1000 C. Model
A-400 operates up to 1500 C.
Each has two electric heating elements inside the bath to rapidly
heat the medium to any desired temperature within the designated
ranges. A cooling coil, when connected to tap water or a cooling
system, permits operation below or slightly above ambient temperature.
A special selector switch provides rapid selection of 10 of the
most popular temperatures. By switching to the "variable" setting,
any temperature within the operating range can be obtained. The
top cover of both models contains seven holes, 5.1 cm (2 in.) diameter
for insertion of viscometer holders. Two additional holes, 1 cm
(3/8 in.) diameter are provided for thermometers. These baths are
designed to be used with water or oil (not supplied). Viscometers,
holders and thermometers should be ordered separately. Applicable
Standards: ASTM D-445

Softening
Point Apparatus
The Softening Point Apparatus uses the ring and ball method for determining
the softening point of asphalt, tars and most resins. Samples are held
within the horizontal rings and steel balls are placed on the top of the
samples. As the sample is submerged in water and heated, the weight of
the ball forces the sample downward. The softening point is the temperature
at which the sample falls 1 in. to bottom shelf. The Softening Point Apparatus
includes (2) standard balls, (2) shouldered rings, (1) 800 ml Pyrex beaker
graduated from 50 to 750 ml, (2) shelves with support rings, ball retaining
rings and metal cover. Applicable Standards: ASTM E 28, D 36, D 2398 |

Church Flasks
The Church Flask is used for the distilling of cut-back asphaltic products.
Rubber stoppers, #5 are purchased separately. 500 ml capacity.
Hubbard-Carmick
Specific Gravity Bottle
The Hubbard-Carmick Specific Gravity Bottle is Erlenmeyer in design for
use with viscous fluids, semi-solid bitumens and emulsions. It comes
with a 24/12 ground glass stopper 40 mm diameter x 55 mm high and has
a 25 ml capacity. Applicable Standards ASTM D 70, D 115, D 234, D 1429

Water Determination Apparatus
The A-500 Water Determination Appartus determines the water in petroleum
and bituminous materials. Includes: s (1) 500 ml borosilicate glass flask
s (1) 15 3/4 in., 400 ml capacity glass con denser with sealed jacket
and outlet tube ground to a 600 angle s (1) glass trap graduated from
1 to 2 ml in 0.1 ml subdivisions and 2 to 10 ml in 0.2 ml subdivisions

Electronic
Flash Point Tester
The Flash Point Tester is used to accurately determine the flash and
fire points of oils, tars, residues and other viscous materials. It offers
a uniquely modern design with stainless steel construction for easy cleanup.
Extra insulation ensures the work area will remain comfortable even at
highly elevated temperatures. A built-in dual speed stirrer is preset
to conform with ASTM D 93A (low; 90 - 120 rpm) and D 93B (high; 250,
+10 rpm). Solid state electronics give precise, repeatable results. Controls,
located on the back panel, are easily accessed and give immediate indication
of testing conditions. Includes two thermometers. Applicable Standards:
ASTM D 93A, D 93B
