Robust magnetic stirrer for general heating and stirring tasks in the laboratory. Suitable for stirring volumes of up to 5 litres. The stirring position made of ceramic is resistant to chemicals and scratches, and is easy to clean. Two illuminated indicators signal when the heating plate reaches over temperature, or the stirring system is not working correctly. A warning symbol indicates when the temperature of the plate is above 50 °C, even if the heating function is not active. The SpeedServo™ torque compensation keeps the speed constant even if the viscosity changes.
