Description
Heat-On 3 Litre Attachment is a dedicated laboratory heating block for applications in which a 3 litre round-bottom flask must be heated under controlled conditions. It supports continuous use at temperatures up to 260 °C and includes a small side bore so that a temperature sensor can be positioned for accurate process measurement. For efficient reactions without media loss, solvent volumes of up to 1,5 L are recommended. Optional safety handles, available separately, enable comfortable and secure transport of the attachment, particularly when it is still hot. This Heat-On accessory from manufacturer Heidolph is intended for routine thermal work such as synthesis, sample preparation, and other flask-based heating tasks where stable heat transfer and probe access matter. The geometry is matched to a 3 litre round-bottom flask, helping laboratories standardise larger-scale heating setups. Supplied as one piece, it fits workflows that require a robust, flask-specific Heat-On solution with clear temperature-monitoring capability and optional handling accessories for safer day-to-day use.

Questions about Heat-On 3-l block
What is this article?
Heat-On 3-l 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.
