mBar and below, the
display will show the actual vacuum.

indicating that samples may be added.
Manual Start-Up
To manually run the freeze dry process press the
REFRIGERATION MAN switch. This will start
the refrigeration compressor. The green LED
above the switch will illuminate. When the
collector temperature reaches the desired
temperature the vacuum pump may be started by
pressing the vacuum switch.
Adding Sample
The following procedure should be followed when
freeze drying samples with a drying chamber or
manifold:
1. 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).
2. Connect a pre-frozen sample to a valve on the
drying chamber or manifold using an adapter.
After connecting a pre-frozen sample to a
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.
