5 Insert aspiration tubing into aspiration filter and
screw together
Insert the aspiration tubing with clamping screw (18) through the
filter mount (17) into the aspiration filter 6.2821.090 (19). Screw
filter mount (17) and clamping screw (18) together until they are
fixed to the aspiration tubing. The tubing end should contact the
bottom of the aspiration filter, to prevent the formation of an air
cushion. Proceed as follows:
• Place the aspiration filter with attached
filter mount on a flat surface.
• Insert the aspiration tubing with
clamping screw top down into the
aspiration filter, until the tubing end
contacts the bottom of the filter.
• Screw filter mount and clamping screw
together.

Screw the other end of the aspiration tubing (with pressure
screw and flange) to an Eluent Inlet In (5) of the degasser (Ini-
tially, screw it in loosely by hand, then tighten it by using the
wrench ¼" 6.2621.050 (also included in the standard equipment)
to rotate the screw a further ¼ turn).

To connect degasser and pump, the tubing connection
6.1834.030 is used. Screw the tubing end with pressure screw
and flange to the corresponding Eluent Outlet Out (6) of the
degasser (Initially, screw it in loosely by hand, then tighten it by
using the wrench ¼" 6.2621.050 (also included in the standard
equipment) to rotate the screw a further ¼ turn). Connect the
other end with the pump.
