Magnetic Stirrer with Heating Jacket RSM-12 – Round-Bottom Flasks and Beakers – 250 ml

The magnetic stirrer with heating jacket RSM-12 combines precise stirring function with efficient heat supply in a compact laboratory vessel. The devices enable flexible configurations as a pure magnetic stirrer or with interchangeable heating jackets for various vessel sizes and shapes – ideal for chemical syntheses, reaction control, and temperature-controlled mixing processes.

The maintenance-free DC brushless motor provides robust and reliable stirring performance over long periods of use. The strong integrated magnet enables effective mixing even at higher viscosities. The high-quality heating jacket made of aluminum silicate cotton ensures uniform heat distribution and fast heating time. The LCD display continuously shows temperature and speed.

The robust metal housing with porcelain coating offers optimal resistance to chemicals and temperature changes. Two independent safety circuits provide continuous device monitoring and ensure safe laboratory work. The hot surface indicator signals temperatures above 50 °C even when the device is switched off and increases workplace safety. The device is supplied with stand and PT-1000 temperature sensor.
