It's capable of handling high viscosities up to 50,000 mPas with a maximum torque of 60 Ncm, making it ideal for stirring viscous mediums.
The large chuck diameter supports many shaft types, enhancing its adaptability. Safety is a paramount feature of this device, with integrated circuits that provide a safe stop function in conditions of anti-stall or overload, where over torque protection automatically stops the motor. Additionally, the through-shaft design allows for easy adjustment of the impeller position to suit varying laboratory needs. In the event of a power outage, the stirrer automatically resumes operation at the preset speed once power is restored, ensuring continuity and efficiency. The IP21 protection class provides basic protection against solid objects and dripping water, further securing the unit in active laboratory environments.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
