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
Identical drive units are employed in the Perimax 12 and Perimax 16 pumps, which differ only in the pump head. A stepper motor ensures a highly uniform flow rate.
Speed and direction can be externally controlled via the connector on the back. (analog: 0-5V Vdc)
The Perimax 12 / 16 is very simple to operate. The pump tubing is placed around the pump head and secured at each end in a tubing retainer. Pressure against the tubing in each channel is adjusted with a fine screw on the pressure lever. Function keys are provided for ON / OFF and RIGHT / LEFT rotation. The rotational speed of the pump head is continuously variable via a 10-turn potentiometer. The digital indicator (0 - 999) ensures a reproducible speed setting and, therefore, a precise flow rate. A high-speed key provides for brief operation at maximum speed, for example, to obtain fast flushing of the tubing- out of the tubing when changing to another liquid.
Sets of pre-assembled pump tubes in pairs with a Y connector and retaining clips are also available. One hose of the pair is run around 8 rollers of a half channel, the other hose of the pair around the 8 phaseoffset rollers of the other half channel.
The pump head consists of 12 rolls and a simple and functional tightening mechanism. It can be expanded up to 6 channels, so that at the same time up to 6 tubes (with different sizes) can be clamped. By selecting different tubing diameters, the liquids are transported each with different flow rates. The pump head can be removed with little effort and put on again, depending on which side of the device removed and the liquid to be fed again rotated by 90 deg. .
The drive motor is equipped with a pulse disc and a light barrier. Characterized in the case of the rotational speed parameter changes in the roller head is held exactly at the predetermined value. This arrangement ensures an extremely precise and reproducible adjustment of the liquid feed rate.
