Place the 6.1903.030 stirring bar in the coulometer cell.
Cut the 6.2713.0x0 ground-joint sleeves to the correct length and attach them to the ground joints of the inserts (electrodes, adsorber tube, etc.). Take care to ensure that the edges of the ground-joint sleeves are cut to size cleanly and that there are no fringes. The ground-joint sleeves must not protrude at the lower edge of the ground-joint opening.
Insert the 6.1403.030 adsorber tube into the generator electrode.
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.
Insert the 6.0341.100 indicator electrode into the left ground-joint opening.
Place the 6.1448.020 septum on the front opening of the coulometer cell and fix it in place with the 6.2701.040 screw cap
Tighten the screw cap only enough so that it seals. The septum must not bend.
