General Information regarding performance specifications etc that I found researching on the web:
Thomas Hoover Uni-Melt 6406H Melting-Point Apparatus . FROM MANUFACTURERS LITERATURE: Thomas Hoover Uni-Melt units are designed for fast, reproducible determinations of melting points using glass capillary tubes. Takes up to five samples simultaneously. Electric heater and stirrer automatically disconnect when bath removed from housing. Bath temperature can be brought near anticipated melting point quickly, then raised slowly until melting occurs at reduced heating rate. Reaches 350C bath temperature in 6 1/2 minutes; cools from 300C to 150C in about 11 minutes; five minutes if compressed air line attached to air inlet tube at rear of housing. 500 watt coiled Nichrome heater, adjustable speed stirrer and armored thermometer included in bath assembly and collected in threaded metal head, which mounts on 100 mL beaker. Controls consist of an auto transformer for regulation of heater input, with dial graduated from 0 to 10 in fifty divisions; stirrer rheostat; switch for capillary vibrator and power switch for lamps and stirrer. The Uni-Melt Melting Point unit is electrically heated, transformer-controlled; range from room temperature to 350C. Armored thermometer, 400 mm long; range -10C to 360C in 1C divisions, numbered at each 10C; enclosed in glass sheath. Shorter range thermometers can be used. Periscopic Thermometer Reader assists in observation of bath temperature and melting capillary. Provides 2 x magnification of thermometer scale segment in window approximately 38 mm above center of capillary observation port. Field covers twelve to fifteen degrees of scale when using thermometer with complete apparatus; covers approximately four degrees of the shorter range thermometers. To track mercury level, upper mirror of periscope raised or lowered by turning knob on rea
