8.8.1 Peristaltic pump

D A N G E R

 

Electrocution hazard. Always make sure the analyzer is turned off and power is disconnected
before installing this option.

The peristaltic pump is a compact tubular pump with a constant output. The flow rate is
determined by the diameter of the tube being used (see 

Table 8

). It is constructed in a

manner that ensures a constant and accurate flow rate, ideal for tasks requiring an
accurate dosing of reagent.

Cassette

The Delrin

®

 cassette can be easily raised and adapted to the size of the tubing. The

bottom is equipped with 2 lateral ridges to prevent any excessive crushing of the pump
tubes. The cassette is not resistant to acids or high concentration reagents. In the event
of leakage, remove and rinse thoroughly with water.

Tubing

The Tygon

®

 tubing has been specially designed for use with this cassette. The smaller

diameter tubes have fittings on the ends for easy connection to larger tubes. The tubing is
supplied with 3 fixations in order to secure the tubing in the cassette and prevent it from
twisting. The tube diameter is color coded:
