„
Screw the connector into one port on the front of the Vacuum Degasser
(Channel A, for example). The direction of flow through the Vacuum Degas-
ser is not critical.
Note
Plastic connectors should only be tightened by hand - over-tightening
them will damage the threads.
„
Repeat the steps above to connect additional titrant lines.
„
Once all required titrant lines have been connected to the Vacuum Degasser,
plug all unused ports with the spare plugs supplied. Press these in by hand.
Caution!
DO NOT prime the membranes by pushing titrant through the degassing
systems. This technique can generate several hundred pounds of pressure
which might rupture the Teflon AF® membrane. The maximum recom-
mended pressure on the membrane is
0.7 MPa ( 100 psig, 7 Bar ).
„
Prime the system using the prime procedure used in the normal set-up and
operation of the MPT-2.
Connecting the Vacuum Degasser in a Typical
System
The following illustration shows the tubing connections that are typically made
between the Vacuum Degasser and the
MPT-2 Autotitrator . The direction of
flow through the Vacuum Degasser is not critical.
