Description
The MS?H?Pro+ LCD Digital Magnetic Hotplate Stirrer is a robust and versatile lab instrument engineered for consistent mixing and reliable heating of liquids. It uses a maintenance?free brushless DC motor to deliver stable stirring speeds up to 1500?rpm and can handle large volumes of liquids (up to 20?L of water) with strong magnetic adhesion. Temperature is digitally controlled from ambient up to 340??C, with safety?focused features such as automatic overheating protection and a visual ?HOT? warning when the plate remains hot after use. The high?resolution LCD display provides simultaneous feedback on set and actual temperature and stirring speed, and the work plate?s ceramic coating resists chemical corrosion and facilitates easy cleaning. Optional external temperature sensing and PC connectivity further enhance experiment control and data tracking for advanced lab workflows.
