4 Connecting the capillaries to the pump tubing for the filtrate
￭ Tighten the PTFE capillary (6.1803.050) to the inlet of the pump
tubing with orange/yellow stoppers (6.1826.320) using a pressure
screw (6.2744.070).
￭ Tighten the PEEK capillary (6.1831.060) to the outlet of the pump
tubing with orange/yellow stoppers (6.1826.320) using a pressure
screw (6.2744.070).
5 Connecting capillaries to the ultrafiltration cell
CAUTION
Use only PVDF pressure screws (6.2744.000) to tighten capillaries
to the ultrafiltration cell.
PEEK pressure screws are too hard and could damage the ultrafil-
tration cell material.
￭ Tighten the PTFE capillary (6.1803.060) to the inlet labeled IN of
the ultrafiltration cell's lower chamber using a PVDF pressure
screw (6.2744.000).
￭ Tighten the PTFE capillary (6.1803.080) to the outlet labeled OUT
of the ultrafiltration cell's lower chamber using a PVDF pressure
screw (6.2744.000).
