finding its way into the sample vessel.

Figure 8 Preparing the drying flasks
Prepare the two drying flasks as follows:
1
Fill both 6.1608.050 drying flasks with 6.2811.000 molecular
sieve.
2
Screw one 6.1821.040 filter tube into each of the 6.1602.145
drying flask caps from below. Tighten the filter tubes by hand.
3
Screw the two drying flask caps with the filter tubes onto the drying
flasks. Tighten the caps by hand.
NOTICE
If drying flask caps or filter tubes are not tightened well, the gas
flow may not be precise and regular. An error message displaying
an erroneous gas flow usually appears when there are leaks in the
threaded connections.
