Inserting a PEEK capillary into the measuring head
1 Feed the capillary through the opening (5-28) of the measuring head
insert.
2 Slide the pressure screw over the capillary. Ensure that the capillary
protrudes 1 to 2 mm from the tip of the pressure screw.
3 Push the capillary into the threaded opening SMP (4-5) of the mea-
suring head connector plate until it stops.
4 Only then start turning the pressure screw, while holding the capillary
firmly in place.
5 Cut the capillary to the desired length using the capillary cutter.
In order to prevent diffusion between the solution in the capillary
and the solution in the measuring vessel, make sure that the end of
the capillary is positioned above the measuring solution.
