Description
RSM-12-B 250 magnetic stirrer (3 l) with heating mantle for 250 ml beakers (low form) combines magnetic stirring with mantle heating for controlled thermal processing of samples in low-form 250 ml beakers. The system is specified for a 3 l stirring capacity class and is supplied complete with a PT-1000 temperature sensor and stand, supporting accurate temperature monitoring and stable vessel positioning during heated mixing. This configuration is intended for laboratory workflows that require simultaneous agitation and mantle heating of beaker contents, such as dissolution, digestion-style preparation or temperature-controlled reactions in standard low-form glassware. Offered as 1 pc from manufacturer Phoenix Instrument, the unit integrates stirring, heating mantle, sensor and stand into a practical bench setup for chemistry, materials and analytical laboratories. It suits routine and research environments where reproducible heated stirring of 250 ml low-form beakers is required without separate assembly of mantle, probe and support hardware.

What is this article?
RSM-12-B 250 Magnetic Stirrer (3 l) with heating mantle for 250 ml beakers (low is the article on this page. Luminix Health distributes Phoenix Instrument for laboratory use. It sits in Manchons chauffants, inside Chauffage, séchage et refroidissement, in Instruments de laboratoire.
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.
