Fix the solvent hose to the solvent connection on the left of the instrument by pushing it on the
connector and tightening the knurled screw.
Fig. 5.6: Solvent hose connection
The solvent hose consists of two parts, a transparent Tygon hose (with FEP veneer) and a white PTFE
hose. The PTFE hose is solvent resistant, thus it has to be inserted into the Tygon hose.
NOTE
Only the PTFE hose must come into contact with solvent, see picture below.
The solvent container should be placed in a
lower position than the instrument.
