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 service life of the pump
tubing depends on the contact pressure, among other factors.
Setting the contact pressure correctly
1
￭ Fully loosen the contact pressure lever , i.e. press it all the way
down.
￭ In the software, activate the drive of the peristaltic pump with the
desired speed.
￭ Raise the contact pressure lever one step at a time until liquid
flows.
