Description
Heating mantle WHM for 250 ml is a laboratory housing heating mantle designed for round-bottom flasks of 250 ml capacity. Equipped with a built-in power controller, it covers a temperature range of 450 °C, delivers 140 W and connects to a 230 V supply. The unit is offered as a single piece with a net weight of 1,093 kg and is intended for controlled heating of glassware in chemical and analytical laboratories. Its housing construction places the heating element and controller together so a 250 ml round-bottom flask can be heated evenly without open flame. This WHM mantle from manufacturer Witeg is suitable for distillation, extraction, reflux and related thermal procedures on the laboratory bench. The integrated power controller allows the operator to set heating output according to the process, while the 230 V connection matches common lab infrastructure. Compact and matched to 250 ml flasks, the model provides a practical solution for research, routine analysis and teaching environments that need reliable flask heating.

Questions about Heating Mantle WHM f. 250 ml
What is this article?
Heating Mantle WHM f. 250 ml is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Heating mantles, inside Heating, drying & cooling, in Lab instruments.
A heating mantle cups a round-bottom flask so the heat meets the glass without a bare flame. The flask volume the mantle was knitted for is the specification. A 1 L mantle under a 250 mL flask heats the air, not the liquid.
Temperature equipment either holds a set point or drives a sample toward one. An oven dries. A furnace reaches the temperatures of ashing and melting. A bath surrounds a vessel with water or oil. A circulator moves that fluid. An incubator holds the mild warmth of a culture. An autoclave uses steam under pressure to sterilise. The number that matters is the temperature the article actually reaches, not the number painted on the dial. Temperature is part of the international system kept by the BIPM and compared by EURAMET.
