FUNCTIONAL DESCRIPTION OF PETROLEUM LABORATORY UNIQUE EQUIPMENT - continued.
Burnout Furnace. The burnout furnace is used for ASTM tests D-482, D-874 and D-2276. It is mounted on the
roadside countertop and operates on 110V, 60Hz, single-phase power supplied by A1CB12 located in the MAIN
POWER PANEL. The furnace has a maximum operating temperature of 2000°F (1093°C), a capacity of six medium
or three large flasks, eight heat rate settings to vary power to heating plates to accommodate any workload, and an
automatic soak timer with settings from 0 to 4 hours. It is used for heat treating, precipitate drying, ashing, igniting
and fusing. It is supplied with a pyrometer.
Laboratory Ovens. The laboratory ovens are used for ASTM test D-2276. They operate on I 10V, 60Hz,
single-phase power supplied by AICB4 located in the MAIN POWER PANEL. They are mounted on the roadside
countertop. The ovens employ gravity convection as a method of heat transfer within their respective chambers.
They are provided with two highly accurate hydraulic thermostats (one for control and one for high limit safety) from
a single control. This provides a sensitivity to.45°F (.25°C). The ovens have a maximum operating temperature of
437°F (225°C). They are supplied with a thermometer with a temperature range of 0 to 482F (250°C).
Kinematic Viscosity Baths. The kinematic viscosity baths are designed to be used for ASTM test D-445. They
are mounted on the roadside countertop and operate on 110V, 60Hz, single-phase power supplied by AICB5, located
in the MAIN POWER PANEL. The baths each hold six glass capillary viscometers. Their temperature range is from
ambient to 212°F (100°C). The solid-state controllers have a sensitivity of ± 0.01°F (± 0.005°C). Each bath has a
motor driven stirrer to circulate the bath liquid, a pyrex bath jar, thermistor probe, thermometer holder, and stainless
steel part covers, viscometer holders, viscometers and a bath thermometer.
Desiccating Cabinets. The desiccating cabinets are mounted on the roadside wall above the countertop. They
are designed for ASTM test D-2276. The cabinets are constructed of stainless steel with glass side panels. Molded
rubber door gaskets provide an airtight fit for the doors. The cabinets also are provided with manual relief valves.
Analytical Balance. The analytical balance is mounted on the damping vibration support which is located on
the roadside countertop. It is used in the performance of AST,M test D-2276. The analytical balance comes with its
own power supply unit which receives 110V, 60Hz, single-phase power from a convenience outlet in the laboratory
compartment. It is a fully automatic, top-loading balance with up front one-finger control of all balance functions. It
provides digital readout that can be viewed from any angle. The door on top and one on each side make the
weighing chamber fully accessible for formulations and liquid transfer operations. The weighing chamber is housed
in glass for unobstructed viewing.
Harvard Trip Laboratory Balance. This balance is stored in the laboratory cabinets. It is a double-beam
balance. The upper beam is graduated from 0 to 10 grams in 0.1 gram divisions. The lower beam is graduated from
0 to 200 grams in 10 gram divisions. The capacity of the scale is 2000 grams. It has a sensitivity of 0.1 gram. It is
provided with two removable stainless steel pans.
