Heating Mantle, Cole-Parmer HM-200-250, 250 mL

Quickly and safely heat round-bottom flasks to 450C (842F). This simple-to-use heating mantle features a built-in power controller with dial markings from 1 to 10 for repeatability. An amber-coloured "heater on" light and a clear-coloured "power on" light indicate when the heating mantle is in use. The replaceable coiled heating element suspended within a thermal insulating cartridge provides maximum heat transfer and support. Unique ventilation slots and ceramic fibre insulation keep the chemical-resistant polypropylene exterior cool even while in use. A safety earth (ground) screen and double fuses provide added safety.
