Abstract
A dry cryogenic shipping container having a removable absorbent assembly is provided. The dry cryogenic shipping container is structured to be a Dewar'"'"'s flask having a first, outer shell assembly, and second, inner shell assembly disposed within and spaced from the first, outer shell assembly, and a cap. Within the shipping container is an absorbent assembly having a body with a central cavity. The absorbent assembly body is formed by a plurality of removable absorbent assembly elements. That is the absorbent assembly elements are sized to pass through the passage into the space within the shipping container. As such, after use, the absorbent assembly body elements may be removed and the remaining components may be sterilized. After sterilization, new absorbent assembly body elements are inserted into the inner space and the dry cryogenic shipping container is used again.
