Abstract:
1. An apparatus for purging rigid sealable containers for storage of sensitive materials, the containers having a sealable inlet port and a sealable exhaust port, comprising means to connect a source of compressed purge gas to a purge gas inlet on a container, including a main gas flow valve; means adapted to allow purge gas to pass from the source of compressed purge gas to a timing device associated with the main gas flow valve, wherein the main gas flow valve turns off a gas flow after a preselected time, and the timing device can vary a time period between commencement and cessation of the gas flow; and means to detach the apparatus from the purge gas inlet; wherein the main gas flow valve is structured for pneumatic activation and to enable purge gas pressure provided by the source of compressed purge gas to operate the apparatus to purge the container in absence of an electrical power supply.
