4.8.4. Rubber valves
The rubber valves (part no. 121860) enable the connection of
round-bottom flasks, wide-neck filter bottles, or distributors for
ampoules to a manifold or drying chamber. Depending on the
connector of the components, the blue plug can be removed.
1 Locking bolt
2 Connection to freeze-
dryer (e.g. via a manifold)
3 Aeration connection
4 Vessel connection
5 Rubber plug
NOTE! The rubber valves come supplied in an ungreased state.
This is why a thin layer of vacuum grease must be applied to the
connector of the freeze-dryer as well as to the vessel connector
prior to start-up in order to ensure trouble-free operation.
In position (1), the aeration connector is open and the vessel
connector is closed. The accessory will be aerated while the
vacuum inside the drying chamber is maintained. As a result,
vessels can be exchanged without any interruption of the drying
process.
