3.3.6 Fitting the ultrafiltration cell
This section describes initial fitting of the ultrafiltration cell including fil-
tration membrane. Please note Chapter 6.1 when assessing the need to
exchange the membrane and when selecting membranes. The proce-
dure for exchanging a filtration membrane is also described in full in
Chapter 4.2.2.

1 Preparing the ultrafiltration cell
• Remove the ultrafiltration cell 28 from its packaging and remove the
three screwed-on blind stoppers.
• Using the 6.2621.070 Allen key (5 mm), fully undo the 5 screws 32,
disconnect the upper section 29 from the lower section 31 and re-
move the sealing ring 30.
• Thoroughly rinse off the sealing ring, lower section and upper sec-
tion of the ultrafiltration cell with ultra-pure water.
Only ultra-pure water or ethanol may be used to clean the ultrafiltration
cell. Using organic solvents (e.g. acetone) will damage the Plexiglass
cell!
