Note
The pinch valve manufacturer recommends that a vegetable-based oil (e.g.
Castor oil) is used to lubricate the section of tube that is inserted into the
pinch valve. This is done to help minimise friction, though testing by Mal-
vern Instruments has not shown this to be essential.
Size measurements
The tubing is attached to the sizing flowcell (ZEN0023) using threaded inserts. As
with the folded capillary cell above, push
both
tubes down into the pinch valve on
the side of the cell area. Ensure the join between the PTFE and silicone tubing is
within the cell area.
