Caution
The 6.1826.xxx pump tubings consist of PVC or PP and therefore must
not be used for rinsing with solutions containing acetone. In this case,
use other pump tubings or use another pump for rinsing.
4.12.2 Maintenance
4.12.2.1 Pump tubing
The pump tubing used in the peristaltic pump is a consumable whose
service life is restricted.
The LFL pump tubing with 3 stoppers is stretched in the tubing cartridge
in such a way that it comes to rest between two stoppers. This results in
two possible positions for the tubing cartridge. If the pump tubing should
exhibit clear signs of wear, then this can be stretched a second time, in
the respective alternate position.
Therefore replace the pump tubing periodically, or when used perma-
nently approx. every 4 weeks .
Selecting the pump tubing
The pump tubing differs in material, diameter and hence also pumping
capacity. Depending on the application, different pump tubings are used.
The following table provides information on the properties and use of the
pump tubing:
