Operating Manual Freeze Dryer BETA 1-8 LDplus / BETA 2-8 LDplus Installation and Commissioning of the Unit  41

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.
