Additionally, a cover may be secured to the fixture that encompasses an interface portion of the fixture and the vessel. Before and/or during testing, gas in the space between the side and face seals may be evacuated, as well as gas present in an interior area of the vessel. The vessel may be exposed to test gas(es) that is soluble by the plastic material of the vessel before and/or after being secured to the fixture. During testing, test gas(es) desorbed by the vessel may be evacuated, with the molecular flow being measured using a mass extraction unit.
