2.3.9 Tubing connections
The tubing connections on the 788 IC Filtration Sample Processor and
the connection to the injection valve of the 733 IC Separation Center
must be made as follows:
Pump tubings are consumable material with a lifetime which depends
on the contact pressure (see chapter 6.3.3). This is why the tubing
cartridges should be raised completely by loosening snap-action lever

on the right-hand side if the pump is to remain switched off for a
considerable length of time (the set contact pressure remains
unchanged).
The 6.1826.0X0 pump tubing is made of PVC and must not be used
for rinsing with solutions which contain acetone. In such cases, rinse
with different pump tubing or a different pump.
