Abstract
Gas is admitted to an in-container purification unit 202 via an inlet 212 located at or near the gas discharge end 220 of the unit. This feature is advantageous because it allows a liquefied gas container to be filled to a level above the second end of the body of the unit without the problem of dispensing liquefied gas.
