In the laboratory use glove box, the need for some experimental supplies or experimental materials, through the transition chamber to the glove box: larger items through the large transition chamber (standard size ¢ 360 × 600mm):
Smaller through the small transition chamber (standard size ¢ 150 × 300mm):
So how to pass the items into the glove box correctly?
Step1: pass items into the box
(Operation process)
Important tips:
Large compartments are evacuated and refilled via the operating screen:
Small cabin pumping is carried out through the vacuum valve below:
Important tips:
1, remember not to open the inner and outer hatches at the same time;
2, the vacuum state of the transition chamber is very difficult to open, open the door please note;
3, trying to open the vacuum state of the transition chamber will damage the mechanical locking structure of the hatch, the transition compartment filled with outside air, remember not to open the inner hatch, if opened will destroy the atmosphere inside the box, and at the same time may damage the analytical instruments and materials inside the box;
4, should regularly check the mechanical parts and seals to avoid contamination;
5、When using inert gas, please follow the relevant national regulations;
Step2: Remove items from the box
(Operation Procedure)
Important Tips:
When passing plastic bags and small items, make sure they are handled properly to avoid blocking the transition chamber extraction port;
Step3: Uncertainty about the atmosphere in the transition chamber
Important Tips:
1, in the case of uncertainty about the gas atmosphere in the transition chamber, before opening the inner door of the transition chamber, you must carry out three pumping and three replenishment of the transition chamber, otherwise it will destroy the atmosphere in the glove compartment (vacuuming to -1bar for once, replenishment to 0bar for once);
2、When passing plastic bags and small items, make sure they are handled properly to avoid blocking the pumping port of the transition chamber;
