￭ Check whether any air bubbles remain trapped in the ultrafiltra-
tion cell.
If air bubbles are trapped in the cell, then unscrew the PTFE capil-
laries from the filtrate outlet (3-3) and from the sample outlet
(3-5) and wait until the air bubbles have escaped. Afterwards,
tighten the capillaries to the ultrafiltration cell again.
