Abstract
A fluid-tight container holding active getter and non-sorbable gas at a pressure of at least about one atmosphere, with gas flow passage means through a wall of the container providing communication between the active getter and the container-surrounding environment, and removable closure means for the gas flow passage means. The container may be opened for gas flow communication and exposure of the active getter prior to sealing of a vacuum enclosure in which it is installed, without significant loss or impairment of sorptive capacity of the getter.
