Heidolph Hei-FLOW Expert 120 -- EU cable

The pump drive of the Model 120 of the Hei-FLOW Expert series can be operated with either single-channel or multi-channel pump heads. The flow rates with single-channel pump heads range from 0.38 - 813 ml/min; with multi-channel pump heads from 0.005 - 329 ml/min. The integration of an analog interface makes it possible to control all functions externally. In addition, an optional foot switch can be adapted to enable dosing by foot pressure. This leaves the hands free to perform other tasks, such as holding the tube and vessel. A speed of 5 - 120 rpm with a control accuracy of ±3.5% guarantees optimum process results.
