TM 10-6640-239-13 1-30 1-13.    FUNCTIONAL DESCRIPTION OF SUPPLEMENTAL PETROLEUM LABORATORY UNIQUE EQUIPMENT. The following paragraphs describe some of the equipment mounted or stored within the Supplemental Petroleum Laboratory. For equipment not described in these paragraphs, refer to the appropriate equipment manual. a. Analytical Balance.  The analytical balance is mounted on a damping vibration support which is located on the roadside countertop and is used in the performance of ASTM 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. b. Autotitrator.  The autotitrator is a complete analysis station for titrimetric analysis and is stored in laboratory cabinet A2.  It enables a titration to be performed and evaluated automatically.  The autotitrator features a simple easy to understand operation.  The setup procedure for a particular analysis avoids the use of technical instrument parameters, which would be unfamiliar to a chemist.  The autotitrator allows storage of 50 complete methods for performance and evaluation of a titration.  The autotitrator is stored in the laboratory cabinets and is operated from 110V, 60Hz, single-phase power from a convenience outlet in the laboratory compartment.  Refer to vendor manual for calibration requirements. c. Automatic Distillation Apparatus.  The automatic distillation apparatus is mounted on the curbside countertop and is used for ASTM test D-86.  The automatic distillation apparatus functions are controlled by a microprocessor.  For programming the required data for the distillation, there is an operating panel and the programmed data can be checked directly by a display.  Analysis of DG0 thru DG6 distillation groups can be programmed (which include benzines, aviation turbine fuels, diesel fuels, gas oils, furnace oils, solvents, aromatics, and crude oil).  The automatic distillation apparatus operates from 110V, 60Hz single-phase power. Refer to vendor manual for calibration requirements. d. Burnout Furnace.  The burnout furnace is used for ASTM tests D-482, D-874 and D-2276 and is stored in overpack box 3.  It operates on 110V, 60Hz, single-phase power from a convenience outlet in the laboratory compartment.  The furnace has a maximum operating temperature of 2000F (1093C), 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. e. Calculator.  The calculator is stored in laboratory cabinet M2.  It has both a display and a built-in printer.  It is solid state and operates on four "AA" alkaline batteries or an AC adapter that will plug into a 110V, 60Hz, single-phase convenience outlet. f. Carbon Residue Tester, Ramsbottom.  The carbon residue tester is located in the left most fume hood and is used to determine the deposit forming or coking tendencies of fuels after pyrolysis in accordance with ASTM test D-524.  This method determines the amount of carbon residue left after evaporating an oil under specified conditions, and is intended to provide an indication of the relative carbon forming propensity of the oil.  The apparatus includes a cast iron furnace block 5” in diameter with 5 sample wells for Ramsbottom glass cooking bulbs.  The block is insulated 4” on the sides, 2” on the bottom, and 1.125” insulating disks on top for safety at high temperatures.  Two 850 W heaters bring the apparatus quickly and accurately to testing temperatures. Temperature is controlled precisely over a 0 to 1999F (-18 to 1093C) range by a type K thermocouple with leads to connect to the digital controller located on the roadside countertop next to the fume hood.
