Heidolph Peristaltic Pump Hei-FLOW Expert 120
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.
Multi-Channel Operation
- Increase your throughput by running up to 12 individual cassettes on one single pump drive and pump head system
- Separate metering into multiple vessels with different feed rates in a single operation by using different tubing dimensions to adjust flow rate
- Save time: tubing change is done in just seconds
- In addition to standard pump heads which feature a 4-roller system you can choose 8-roller pump heads for low pulsation
- Change your cassettes easily, even during operation – there are no restrictions
- Cassette adjustments and changes are simple, just click in place
- No additional purchase of a pump drive needed: upgrade your single-channel pump drive with just one adaptor for multi-channel use and pick the head/cassette configuration that matches your application needs
