The Perimax peristaltic pump is used in all branches of analytical and preparative chemistry, and in production systems:
Analytical instrumentation
Biotechnology, bioanalytical chemistry
Liquid chromatography
Column chromatography
ICP and AA instrumentation
Liquid transfer, dosing and mixing
Laboratories and production
The principle behind the Perimax 16 - Antipuls peristaltic pump permits pulsation-free operation. Two tubes that pass over a roller head and whose rollers are arranged phase-shifted relative to one another are brought together. As a result, the peaks and troughs cancel one another out, thus resulting in a completely pulsation-free flow.
The roller head with its 16 rollers consists of 4 half-channels with 8 rollers each, with two phase-shifted tubes always being combined. The pump can be operated with two low-pulsation channels, four pulsed channels or one low-pulsation and two pulsed channels.
Control
The rear-mounted connector can be used to control the speed and direction of rotation by means of an analog 0-5 V signal.
Operating the unit
Operation of the Perimax 16 peristaltic pump could not be easier. The tube is guided around the pump head and its two ends are fixed to a special mechanism. The compression level is set using an adjusting screw at the adjusting lever. There are operating buttons to switch the pump ON or OFF or to run to the RIGHT or LEFT. The speed of rotation of the pump head can be continuously adjusted using a 10-turn potentiometer. The digital display (0 – 999) ensures a reproducible speed of rotation and fluid delivery rate.
