The ability to switch between precise dosing and fast conveying make this pump model the perfect complement to a reactor system. With a flow rate of 2.0 - 4,056 ml / min, when operated with single-channel pump heads, flows from feed-batch and chemostat modes of operation can be conveyed precisely. Rapid filling and emptying of the reactor system is also possible.
In addition to the selectable process parameters - speed, tubing diameter, flow quantity display, dosing volume, interval dosing and break times - the pump conveying characteristics are stored in the program. Thanks to the analogue and digital (RS 232) interfaces, processes can be automated.
All media is conveyed with a control accuracy of ±0.5% at a speed of 24 — 600 rpm. An optional foot switch can be connected for dosing by foot pressure.

When used correctly, no air bubbles emerge in the tube. The end of the tube must be deep enough in the container, from which the substance should be pumped.
With our Hei-FLOW peristaltic pumps, the high precision achieves minimum flow rate of only 0.005 ml/min.
