C i g a r e t t e smoking machines, designed by The American Tobacco Co., are now in general use as a standard t o o l . The smoke is filtered and the amounts of solids and nicotine are determined
WALL COOLING is employed rather than a coil! Heat transfer is spread over a large area, and consequently there is a minimum temperature differential. Faster cooling or heating. Wide opening. No room is lost to a coil and diffuser panel. VERSATILE WACO BATH is used as a reaction site for organic syntheses, as a bath for the determination of physical constants, for bio-chemical procedures, ASTM tests, etc., for supplying constant temperature circulant to viscosimeters, refractometers, etc. A 3i2 h.p. hermetically sealed compressor is used. An easily adjustable magnetic-setting mercury triermoregulator provides temperature control of ± .05° C. Heating element permits operation above room temperature. Inside dimensions are 29" long X 14" wide X 10" deep. All controls are conveniently arranged at one end.
