2.3.6 Reagent Exchange Adapter
The Reagent Exchange Adapter is used to connect reagent and waste bottles to the titration
vessel. The adapter consists of a set of o-rings and compression caps that form a seal around
the reagent and waste tubes, and a ground-glass joint for connection to the titration vessel.
The compression caps can be loosened when inserting tubes or adjusting the tube position
and tightened to hold the tubes in place. To set up the Reagent Exchange Adapter (see Figure 7):
(1) Loosen the compression caps on the Reagent Exchange Adapter so that the
o-rings uncompress.
(2) Slide the blue PTFE reagent tube (from the reagent bottle assembly) through the
cap and o-ring on the right-angle side of the Reagent Exchange Adapter. At least
1 inch of tube should be inside the adapter.
(3) Tighten the cap until the reagent tube is held in place.
(4) Slide the blue PTFE waste tube (from the waste bottle assembly) through the cap
and o-ring on the straight side of the Reagent Exchange Adapter. At least 1 inch of
tube should be inside the adapter.
(5) Tighten the cap until the waste tube is held in place.
(6) Place the Reagent Exchange Adapter into the holder.
