Operating Manual Freeze Dryer ALPHA 1-2 LDplus Description of the Freeze Drying Processes • 23
Sealing of the ampoule is carried out in the same way. The hose of
the ampoule to be sealed is clamped and the ampoule is sealed
under vacuum using the blow lamp.
If the ampoule breaks during sealing the vacuum in the drying
chamber is not affected due to the clamping with the hose clamp.
The remaining glass from the ampoule is removed and the hose is
closed with a blind plug.
In this way one ampoule after the other can be sealed or new
ampoules can be connected.
