– Push the locknut onto the pump tubing.

3 Inserting the pump tubing
￭ Press the tubing cartridge's contact pressure lever down all the
way.
￭ Place the pump tubing in the tubing cartridge. Fit the tubing car-
tridge between two stoppers. The stoppers must snap into the

cartridge holder until you hear the snap-action lever snap in.
Setting the flow rate
The flow rate of the peristaltic pump depends on many factors:
￭ The inner diameter of the pump tubing
￭ The rotational speed of the drive
￭ The contact pressure of the tubing cartridge
NOTE
Pieces of pump tubing are consumables. The lifetime of the pump tub-
ing depends on the contact pressure, among other factors.
