Productbeschrijving

IKA Microstar 7.5 control bovenroerder 2 liter 750 mPas;

The first compact and high-performance overhead stirrers with lifetime warranty. Suitable for low viscosities (750 - 8000mPas) and volumes (2-25l). A microprocessor-controlled operation keeps the speed range constant, depending on the model from 0/30 - 500/2000 rpm. Actual and set speed can be adjusted continously. The speed will remain constant even with changing viscosities. A torque trend measurement will show any changes in viscosities of the sample. An electronic safety circuit as well as a state-of-the-art vibration detection guarantees the stirrer to stop when an anomaly is detected. Operating and documenting all parameters, as well as updating the latest firmware are possible by the USB interface.
