For use in micro fusion studies over the range — 100°C to +70°C MICRO COLD STAGE (Micro Melting Point Apparatut), Thomai-McCrone Thermometer
Reading Model. Based on the design described in Analytical Chemistry, Vol. 28, No. 6 (June, 1956), p. 10S8. Provides close temperature control within a working range of -100°C to + 70°C. Bevelled cut-out in top of stage takes a standard 10 X objective. Simplified for convenient insertion of sample and reproducible placement of interchangeable, low temperature thermometers. Heating is by means of a Pyrex brand E-C Radiant Glass plate. Voltage on the heating unit should not exceed 80 volts and a special Variable Transformer is included with the Stage. The manipulator rod for seeding, etc., is inserted into the working chamber through a ball joint. Thermometers are inserted from the side. In use, a stream of inert, precooled gas is passed over the sample and escapes from the stage through a small annular space around the objective. Moisture is removed from the gas stream in a simple Cooling Device, thus minimizing possible icing of the objective.
