Glove Box supports vacuum and degassing operations.

Vacuum cycling provides a fast, economical way to achieve extremely low moisture and oxygen levels inside the chamber. During each cycle, a vacuum pump connected to the glove box removes the chamber environment, and with it moisture and oxygen. At the end of the vacuum cycle, the chamber is backfilled with a clean, dry process gas (commonly nitrogen or argon) to restore neutral pressure. This cycle can be repeated as many times as necessary to attain the desired low humidity, low oxygen conditions.

Glove box  is  fabricated  of  40 mm thick  acrylic and 8 mm SS/Mild Steel features support ribs to minimize wall deflection under vacuum. The chamber comes with a vacuum gauge and three metering valves on the top chamber panel: one for connection to a vacuum pump, one to interconnect the glove port  chambers,  and one  to  bleed  the  vacuum.  Each  glove  port  chamber  includes  its  own  vacuum  gauge  and  dual valves,  one  to  connect  to  the  main  chamber  and  one  to  bleed  vacuum.  Dual  swing  doors  with  latches  isolate  these chambers from the atmospheric pressure, allowing gloves to remain in place during vacuum processing.
