ure 9).
• Insert the second end of the capillary into the waste container
(e.g. optional: 6.1608.070 bottle with 6.1602.150 bottletop GL45).
3 Filtration cell – pump tubing connection
• Fit a PEEK pressure screw 60 to one end of the PTFE capillary 63.
• Screw a coupling 62 onto this pressure screw.
• Fit a PVDF pressure screw 64 onto the other end of the PTFE capil-
lary.
• Fit this end of the PTFE capillary with the PVDF pressure screw to the
outlet opening for the filtrate 36 on the upper side of the ultrafiltration
cell (see Figure 9).
• Fit a coupling 62 onto the inlet end of the pump tubing 61.
4 Pump tubing – injection valve connection
• Fit a PEEK pressure screw 60 to one end of the PEEK capillary 67.
• Screw a coupling 62 onto this pressure screw.
• Fit a coupling 62 onto the outlet end of the pump tubing 61.
• Pull the PEEK capillary 67 through one of the feedthroughs on the
front side of the 820 IC Separation Centre and, using a PEEK pres-
sure screw 60, screw it onto connection "1" of the injection valve in
the 820 IC Separation Centre.
• Close the rotary nipple on the inner compartment side of the corre-
sponding feedthrough and thus fix the PEEK capillary in position.
