The pump head has a unique operating principle whereby the tubes are engaged with the rollers over a section of 95° only. This arrangement allows the installation of two tubes on both sides of the roller wheel with the advantage of 50% space saving, a balanced and much reduced motor load and less wear in the tubes.
Series 4000 pump controllers can be operated in both directions for dispense or suction, at rotor speeds to 340 rpm. Simple controls allow you to dispense or aspirate any volume with high precision and accuracy. Dispense or aspirate protocol can be programmed to repeat in up to 99 steps separated by up to 99 second intervals. Volumes can be calibrated to match a large variety of tube sizes and the display can be adjusted to show the desired working range in ml.DIMENSIONS
4000 & 6000 series peristaltic pumps are built on the unique operational principle of balancing the load on the motor and gearbox shafts. The peristaltic tubes are positioned in pairs on both sides of the rollers.
The pumps are supplied with a standard of 8 rollers per channel. The 8 rollers enhance dispense accuracy and reduce pulsation. As the 8 rollers are step offset between the stages, a link between channels in two adjacent stages will further reduce pump pulsation.
The pumps have 4 channels/tubes per stage and can be supplied in up to 3 stages.
With large supporting bearings on the front and back of the rollers, the construction is ideal for long life and maintenance free operation.
Tubing can be specified from a wide range of diameters. The color coded tube clips are manufactured to match the various tube diameters and thus eliminate the need for any adjustments.
The tubes are generic size tube diameters, which are easily sourced, individually cut to length and easily clipped into the tube holders.
