2.3.4.2 Connecting the Reagent Adapter Holder
The Reagent Adapter Holder is a convenient dock for the Reagent Exchange Adapter when it
is not in use. The holder consists of a base that fastens to the titrator pump bay and a
removable standard-taper glass tube. The glass tube holds the Reagent Exchange Adapter
and will catch possible drips from the reagent/waste tubes. It is easily removable for cleaning
purposes. Install the Reagent Adapter Holder with the following steps (see Figure 2.):
(1) Lower the Reagent Adapter Holder base into the right bay, then slide it towards
the front of the titrator chassis until it is firmly latched.
(2) Secure the base with the locking screw.
(3) Insert the glass tube into the hole in the base. If the tube does not slide easily into
the holder, apply a small amount of glass joint grease (included) to the outside of
the tube for lubrication.
Note: To set up the Reagent Exchange Adapter, see Section 2.3.6.
