Drying tube
Use of a drying tube, filled with a suitable absorbent (purchased
separately), might be necessary for moisture- and CO
media ('Accessories', page 56).
For mounting, unscrew the air vent cap (Fig. a) and screw the filled
drying tube in (Fig. b). Place the PTFE sealing ring on the bottle
thread (Fig. c) and screw the instrument onto the bottle.
Note:
If necessary, seal the threads of the drying tube, the bottle and/or
the bottle adapter with PTFE tape.
Sealing ring for valve block
For highly volatile media we recommend to seal the connection from
valve bloc to bottle with the PTFE sealing ring (see accessories,
page 56).
For mounting, place the PTFE sealing ring on the bottle thread or
the screwed-on adapter (Fig. c) and screw the instrument onto the
bottle.
Air vent cap for micro filter with Luer-cone
For sterile media we recommend the air vent cap with Luer-cone to
attach a micro filter. This provides increased protection against con-
tamination by displacement air (see accessories, page 56).
For mounting, unscrew the air vent cap (Fig. a) screw in the air vent
cap with a Luer cone (Fig. d). Place the PTFE sealing ring on the
bottle thread (Fig. c) and screw the instrument onto the bottle.
Insert a commercially available sterile filter into the Luer cone (Fig. f).
