• Heidolph's lightest overhead stirrer is here - with a torque of 40 Ncm!
• Thanks to its weight of 2.3 kg, the Hei-TORQUE Core is easier to carry than the other models and can be mounted on a stand and/or in various closed systems. However, this does not mean that this stirrer will be less powerful.
• The additional name “Core” emphasizes that it is a model of selected functions and important safety features that provide tangible help with any stirring task. Above all, the Hei-TORQUE Core scores with its simple operation: The quick-action chuck (Quick Chuck) can be opened and closed very easily without a key. The “Max” button allows you to reach the maximum speed of 2,000 rpm in no time. Thanks to the display, you can keep an overview of all application parameters.
• The Hei-TORQUE Core has a quick-action chuck with a diameter of 10.5 mm and can therefore be combined with a variety of stirring tools. To achieve the best possible homogeneity, it is suitable for viscosities up to 10,000 mPas or volumes up to 25 liters (H2O).
