Figure 10 Mounting the adsorber tube
Mount the adsorber tube as follows:
1 Fill the adsorber tube 6.1619.000 with an adsorption material
required for the reagent.
￭ Molecular sieve for moisture-sensitive solutions ( e.g. KF solu-
tions).
￭ Soda lime for sodium hydroxide solution (CO
2
adsorption)
2 Seal the adsorber tube with the appropriate cover.
A minimum pressure compensation remains ensured.
3 Screw the adsorber tube to the deaeration port (VENT) of the dos-
ing unit.
The adsorber tube should be screwed on a bottle in hanging position
after the assembly of the dosing unit.
The VENT connector deaerates the reagent bottle. It should never be
entirely sealed off. If no adsorber material is required, then the adsorber
tube can be filled with cotton and used as a dust filter.
