Description
Heat-On 500 ml attachment is a dedicated heating block insert designed for controlled heating of 500 ml round-bottom flasks in laboratory workflows. Built for continuous operation up to a maximum temperature of 260 °C, it supports reliable thermal performance during synthesis, digestion, and other heated reactions. A small side borehole allows precise temperature monitoring with a suitable temperature probe, helping maintain process control without interrupting the setup. For efficient reactions and reduced solvent loss, solvent volumes up to 250 ml are recommended. Optional safety handles, available separately, enable comfortable and safer handling of the attachment, especially when hot. Supplied as a single piece with a net weight of 1,384 kg, this Heat-On unit from manufacturer Heidolph integrates into standard laboratory heating arrangements where round-bottom flasks must be heated uniformly and securely. Its compact format suits routine organic and preparative work that depends on stable flask seating and consistent heat transfer across the vessel wall.
This article is part of Heating mantles, in Heating, drying & cooling.

Questions about Heat-On 500-ml block
What is this article?
Heat-On 500-ml block is the article on this page. Luminix Health distributes Heidolph 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.
