Operation
Interchange Vacuum
Gauge
An indicating vacuum gauge is mounted on the front panel of the
anaerobic system to show the gas pressure in the interchange. The gauge
continuously displays interchange pressure and is particularly helpful in
monitoring the vacuum and N
2
cycles during transfer.
The manual chamber fill knob is used to manually increase the gas pressure
in the glove box. Turn the knob counterclockwise to open the valve and
allow gas to enter the chamber.
The chamber relief bubbler allows anaerobic gas to leave the chamber if the
gas pressure in the system is too high. The bubbler prevents the entry of
aerobic gas into the system. The chamber relief may bubble when the
operator’s arms are extended into the chamber, or if the gas pressure
becomes elevated for any reason. The chamber relief mechanism protects
the clear front panel from the strain that can be caused by excessive gas
pressure.
A unique memory system monitors the interchange aerobic-anaerobic
status. The two lights on the panel continually display the status of the
interchange.
The (green) Sequence Complete anaerobic light indicates that the
interchange is complete. The interchange is in an anaerobic state. the
(amber) Sequence Not Complete light indicates that the interchange
contains atmospheric gas.
The lights indicate when it is safe to open the inner chamber door. They
also indicate when the interchange has completed a transfer cycle. The
lights indicate interchange status only.
The inner and outer door indicator lights continuously tell the operator
which door should not be opened at a specific time. The lights help the
operator prevent contamination of the chamber with atmospheric gas by
indicating which door is unsafe to open.
