Heating mantles

The mantle must follow the shape of the vessel, because heat only transfers evenly where the vessel touches the mantle. A spherical mantle is made for round-bottom flasks; a flat or cylindrical mantle for beakers, such as the heating mantle for beaker, 1000 ml; and separate mantles exist for reaction vessels, such as the heating mantle for reaction vessel, 1 l. Using a mantle with the wrong shape leaves air gaps and local hot spots. Tell us your vessel and volume: sales@luminixhealth.com.

A built-in magnetic stirrer keeps the temperature uniform in the liquid and prevents local overheating and bumping, so choose it for solutions, reactions and anything that must be heated evenly, such as the heating mantle with stirrer for beakers, 1000 ml. Add a suitable bar from magnetic stirring bars. A mantle without stirrer is enough for simple heating, distillation with boiling stones, or when you stir from above with an overhead stirrer for viscous mixtures. Not sure which fits your set-up? Ask sales@luminixhealth.com.

Choose the mantle by the nominal volume of the flask, not by how much liquid it holds: a 250 ml flask needs a 250 ml mantle. A mantle that is too large leaves the flask loose, so it heats unevenly and can overheat the empty part of the shell. Volumes from small to large are in the product titles, for example the heating mantle, 2 l. If you work with several flask sizes, one mantle per size is the safe choice. For jacketed or reaction vessels, see reaction vessels and jacketed vessels. Questions? Ask sales@luminixhealth.com.

Many mantles have a built-in controller; some only work with a separate control unit, which the product page states, so check this before ordering. For reproducible work, regulate on the temperature of the medium with a probe from temperature probes and sensors rather than on the shell. Support the flask and mantle so nothing tips: a support ring, such as the support ring for standard heating mantle, and a stand with clamps keep the set-up stable, and let you lower the mantle quickly to stop heating.

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.
