4 Insert the 6.0345.100 generator electrode without diaphragm or the
6.0344.100 generator electrode with diaphragm together with the
adsorber tube into the large ground-joint opening at the rear.
5 Insert the 6.0341.100 indicator electrode into the left ground-joint
opening.
6 Place the 6.1448.020 septum on the front opening of the titration
cell and screw it shut with the 6.2701.040 screw cap.
Tighten the screw cap only enough so that it seals. The septum must
not bend.
Filling the titration cell (generator electrode without dia-
phragm)
Proceed as follows when using a generator electrode without a dia-
phragm:
1 Fill approximately 100 mL of reagent into the titration cell using the
6.2738.000 funnel.
2 Close the remaining ground-joint opening on the right with the
6.1437.000 ground-joint stopper (with ground-joint sleeve attached).
Filling the titration cell (generator electrode with dia-
phragm)
Proceed as follows when using a generator electrode with a diaphragm:
1 Fill approximately 5 mL of catholyte into the generator electrode.
2 Fill approximately 100 mL of anolyte into the titration cell using the
6.2738.000 funnel. The level of the anolyte should be roughly 1 to 2
mm above the level of the catholyte.
3 Close the remaining ground-joint opening on the right with the
6.1437.000 ground-joint stopper (with ground-joint sleeve attached).
