Fonctionnement

Sample is placed inside the polycarbonate vessel, optionally on a 230 mm PP shelf. A silicone O-ring is seated between top and base. The vessel is connected to a vacuum source via the quick-disconnect needle valve and evacuated. Once vacuum is established the needle valve is closed — finger-tight gives zero leak at 1 atm. For inert-atmosphere storage, a second needle valve is opened to back-fill with N2/argon while the first valve serves as evacuation. The integral vacuum gauge (top) shows internal pressure. To open, the needle valve is rotated to release vacuum.
