5.7 Removing an Item from the Glovebox Using the Large Antechamber
It is extremely important that the Antechamber contains purified gas because opening the inner
door will expose the box to the Antechamber. If you are not certain of the status of the
Antechamber, then evacuate and refill 3 times before proceeding.
We suggest that you keep the Antechamber under vacuum. This will prompt you to refill before
proceeding.
1
Ensure that the outside door is fully closed.
2
Ensure that the refill valve is closed.
3
Open the inner door.
4
Insert the object into the Antechamber and close the inner door.
5
Open the outside door and remove the object.
5.8 Purge Valves
Manual Purge Valve – As standard the Glovebox is fitted with a hand-operated 2-Way Ball
Valve that is used to manually displace atmosphere from the Glovebox. The valve must be
closed fully after purging process to prevent loss of box pressure.
