SETUP
Reagent Exchange Port
The HI 904 titration vessel can be connected to the reagent and waste bottles using the
Reagent Exchange port and the supplied adapter. The Reagent Exchange Adapter may remain
connected to the titration vessel during operation if lower drift is not necessary. Otherwise,
place the supplied glass stopper (G) in the Reagent Exchange Port.
Sample Port
The sample port consists of a silicone rubber septum (B) secured in place with an open-top
GL18 cap (C). This allows liquid samples to be added to the titration vessel with a syringe
and needle while sealing the vessel from atmospheric moisture. The rubber septum can be
easily replaced as needed by removing the GL18-threaded cap.
