3.6 Antechamber Operation
General Information
The system is equipped with a large (and/or small) antechamber designed for transferring
material into or out of the glovebox without polluting the internal box atmosphere or the room
atmosphere. The antechamber(s) is equipped with an inner door, outer door and sliding tray to
ease in transferring materials.
Transferring material into and out of the box can be done in the Automatic or Manual Modes.
Both modes utilize the antechamber components and the touch screen. The chamber
undergoes several evacuation/refill cycles to clear the chamber of room or glovebox
atmosphere prior to removing the material from the chamber.
• An evacuated chamber cannot be opened. Attempting to open an
evacuated antechamber may damage the door locking
mechanism.
• Keep both antechamber doors closed when not transferring
materials.
