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 are in the range of 0.38 — 813 ml/min; with multi-channel pump heads from 0.005 — 329 ml/min.
By integrating an analog interface, it is possible to control all functions externally. In addition, an optional foot switch can be adapted to enable dosing by foot pressure. Hands thus remain free to perform other work, for example, to hold the tubing and the vessel.
A speed of 5 — 120 rpm with a control accuracy of ±0.5% guarantees optimum process results.
