Assembly the pump tubing
Pump tubing is a consumable whose working life depends on the
contact pressure. This is why when the pump is switched off for a long
time, the tubing cassette should be lifted by fully loosening spring
lever
on the right-hand side (in this way the correctly set optimal
contact pressure is retained).
The 6.1826.0X0 Pump tubing consists of PVC or PP and must
therefore not be rinsed with solvents that contain acetone. In this case
you should either use different pump tubing or use a different pump
for rinsing.
