8.2 Drying tube
Use of a drying tube, filled with a suitable absorbent (purchased
separately), might be necessary for moisture- and CO
media (‚Accessories', page 51).
Assembly
1. Use a coin to unscrew the air vent cap (Fig. 1).
2. Screw the filled drying tube in (Fig. 2).
3. Place the PTFE sealing ring on the bottle thread (Fig. 3) 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.
8.3 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 and PTFE tape (see
‚Accessories', page 51).
Assembly
Place the PTFE sealing ring on the bottle thread or the screwed-on
adapter (Fig. 3) and screw the instrument onto the bottle.
8.4 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 51).
Assembly
1. Unscrew the air vent cap (see ‚Assembly Drying tube', Fig. 1).
2. Screw in the air vent cap with a Luer cone (Fig. 1).
3. Place the PTFE sealing ring on the bottle thread and screw the
instrument onto the bottle.
4. Insert a commercially available sterile filter into the Luer cone
(Fig. 2).
