Freeze Drying Using the Manifold Valves
Some Tray Dryers are equipped with a 6-Port Manifold. The procedure below
should be followed when freeze drying samples using the manifold.
1.
Close and latch the Stoppering Tray Dryer door.
2.
Set the Vac Release valve to CLOSE.
3.
Pre-freeze samples - Shell freezing of samples is recommended.
Appropriate containers for freeze drying includes ampules, serum bottles,
and wide mouth freeze drying flasks. Proper sample container size should
always be at least two to three times the sample size (i.e., 150 ml samples
should be prepared in 300 ml containers or larger).
4.
Start the Freeze Dryer in either the Auto or Manual mode (See the Freeze
Dryer User’s Manual)
5.
Connect a pre-frozen sample to a valve on the manifold using an adapter.
Some vials can be attached directly to the sample valve. Turn the plastic
valve knob to the “VACUUM” position to open the valve, which connects
the attached sample to system vacuum. The bevel on the knob should be
positioned toward the sample port.
