Container for storing solid living tissue portions

摘要

A wide-mouthed flexible, collapsible, sterile bag made of sheeting of poly (ethylene-vinyl acetate) containing from 5 to 35 weight percent of vinyl acetate units. The bag is made to be used for storing solid, living tissue portions at cryogenic temperatures. The wide mouth of such a container may be heat sealed prior to storage. Such containers, while flexible and collapsible, exhibit effective strength and durability at such cryogenic temperatures.
