1. Fill 6.1608.050 drying bottles 15 with 6.2811.000 molecular sieve
and place 6.1821.040 outlet tube (with 6.2821.090 filter) in
6.1602.140 screw cap. Screw the screw caps onto the drying bottles.
When attaching the tubing please

bottle at the top of the bottle. Connect the other
end of the tubing to the air/nitrogen outlet 14
(see drawing).
3. The rear drying bottle is connected to the front
bottle using 6.1805.010 Tubing (13 cm). Screw
the tubing onto the outlet tube of the front bottle
and connect the other end to the inlet connec-
tion of the rear drying bottle. The carrier gas
must enter the rear drying bottle at the top of
the bottle.
4. Screw 6.1805.020 Tubing (52 cm) onto the
outlet tube of the rear drying bottle and lead it
through the tubing guide on the guide head of
the 832 KF Thermoprep. The free end of the
