The robust and reliable overhead stirrers of the Hei-TORQUE series are designed for maximum longevity and highest safety.
Our powerful motors guarantee the best mixing results and a shorter process duration, and their highest safety features mean that they can be used for unattended continuous operation.
The maintenance-free motors as well as the sealed housing reduce maintenance and repair costs, over its 10-year average lifespan.
By investing in Heidolph products you have chosen premium laboratory equipment, backed by a 3-year warranty.
With the new Quick-Chuck, you can change impellers in a matter of seconds with one hand. No unpleasant searching for a chuck key and no risk of the impeller sliding down. With the Quick-Chuck, you have everything under control and do not need any extra tools.
With a clear display and the easiest handling,
it is ideal for every standard application
Are you looking for a reliable stirrer that is extremely easy to use?
The Hei-TORQUE Value overhead stirrer is clearly easy to handle. The simple interface combined with high performance is its hallmark. Every mixing process can be simply adjusted. Whether low or high viscosity, it manages any media with ease. Choose the right stirrer for your application from a wide range of powers, right up to the 400 Ncm model, which features a two-stage gearbox for several torque ranges.
The powerful motors ensure excellent mixing results, even in very viscous media. The rotational speed remains constant even if there are large fluctuations in viscosity. In case of permanent overloading, the overtemperature protection intervenes and switches off the motor - for your safety.
Is safety and simplicity important to you?
If you demand a simple interface, the strongest power,
and maximum robustness from an overhead stirrer, the
Hei-TORQUE Value is the overhead stirrer for you.
The Hei-TORQUE Value is equal in every aspect to the Hei-TORQUE Precision in terms of mixing performance. Simple to use, this basic model from the Heidolph range of overhead stirrers is a popular choice for many standard applications.
Ideal for every application with highest safety requirements where reproducible and documentable results are needed
Are you looking for an individually adjustable stirrer for reproducible results?
The Hei-TORQUE Precision is the function-rich counterpart to the Value model. It has added powerful options with precise settings and additional features. These include saving processes for reproducibility.
Do you work with low-viscosity fluids and require highest safety standards?
Adapt the start operation to your needs:
The stirrer starts gently to prevent fluids splashing. You define a maximum rotational speed that must not be exceeded. This prevents the beaker from overflowing.
Do you work with high-viscosity media and glass impellers?
Protect your glass impellers from breakage with an individual torque limit. Adapt the starting characteristics to the viscosity.
Do you want to save processes with intervals and ramps while documenting precisely what occurred?
With the Hei-TORQUE Precision, you can program profiles with or without ramps, save them on your device as favorites and use them in the interval operation. Monitor the process flow using graphs. Detect every change in viscosity with the precise torque display. Calibrate the torque for precise documentation. Calibration involves adjusting the output value to the ambient conditions.
Do you need reproducible documentation?
Via RS 232 and USB interfaces you can control every
Hei-TORQUE Precision directly from your PC with the new
Hei-Control software. A USB cable plus the software are included in the scope of delivery.
The new Hei-Control Software* enables you to:
