CryoSorb Sorbent Retainers are widely used in the insulating annulus of many cryogenic storage vessels manufactured today. CryoSorb Sorbent Retainers have a very high affinity for trace atmospheric gases such as nitrogen, oxygen, and carbon dioxide at cryogenic temperatures.
CryoSorb Sorbent Retainers will pump vacuum insulating areas in cryogenic storage vessels down to less than 1/10 of a micron, absolute pressure, after taking over when the mechanical evacuation equipment is sealed off and the retainer is pierced.
