6428U05

Provide precise melting point up to 500°C

 • Castings conduct and radiate heat evenly to capillaries
and thermometer

 • Integrated light and 6x lens for enhanced sample
observation

 • Extruded aluminum housing

To use, insert charged capillaries and adjust the heating rate. When sample melts, record the temperature. Units accept up to three capillary tubesand each capillary is heated on three sides. Heating rate control is continuously adjustable with built-in variable transformer. The block is made from a highly conductive alloy to prevent hot spots. Durable, top quality components are mounted on a 1/₈ " thick aluminum panel. Panel markings are etched to prevent fading or wear. Dimensions (L x W x H, cm): 14 x 11 x 22. Power requirements: 100-120 V, 200 Watts or 210-250 V, 200 Watts.

All Mel-Temp units include a heat guard. Thomas numbers 6428U05 and U07 include a glass thermometer. Thomas numbers 6428U09 and U11 include a digital thermometer that uses a low mass thermocouple (that occupies the left capillary slot) to reduce thermal lag. This allows melting points to be determined faster without sacrificing accuracy. The thermometer has a resolution of 0.1°C. A “Hold” key allows uninterrupted observation of the sample.
