drying flask covers from below. Tighten the filter tubes well by
hand.

Screw the two drying flask covers with the filter tubes onto the dry-
ing flasks. Tighten the covers well by hand.
Note
If drying flask covers or filter tubes are not sufficiently tightly
screwed on, then this will prevent a precise, regular flow of gas.
The error message "Flow rate error" will appear as a rule when
there are leaks in the threaded connections.

Mount the FEP tubings as follows:

Load the two drying flasks that have been prepared into the holders,

(at the front, labeled 1). Screw the other tubing end on the front dry-
ing flask to the M6 connector without point marking (see left-hand
