A cryogenic shipping and storage system includes a cryogenic dewar having a top opening, one or more specimen holders suspended within the dewar, a top housing secured to dewar opening and forming a central opening corresponding with the top dewar opening to allow insertion and withdrawal of the one or more specimen holders, a plug adapted to engage the one or more specimen holders and close the central opening of the top housing, a top cover hingedly carried by the top housing over the central opening, and indicia provided on the top housing to identify each of the one or more specimen holders suspended within the dewar. The top housing includes means for detachably receiving and maintaining the spaced relationship of the one or more specimen holders suspended within the cryogenic dewar. The specimen holder includes an elongated support having a tortuously shaped portion to permit the unobstructed removal of the specimen holder from the interior of the dewar and a dewar-engaging portion projecting from the elongated support so that, when the specimen holder is suspended within the dewar, the specimen holder is urged by gravity away from contact with other specimen holders secured within the dewar.

A cryogenic dewar for shipping refrigerateable materials, said dewar including an outer casing and an inner vessel with each having small openings at their tops connected together by an air-tight neck portion forming an evacuable space between the outer casing and the inner vessel and a dewar opening into the inner vessel, said evacuable space containing thermal insulating material to inhibit the transfer of heat therethrough, characterized by: a specimen holder comprising a canister having a central axis and an elongated support, said elongated support being connected at one end to one side of the canister and having at its other end a projecting portion extending generally over and beyond the central axis of the canister with a dewar-engaging portion that lies sufficiently beyond the central axis of the canister so that, when the specimen holder is suspended within the dewar through said dewar opening by the elongated support, the canister is urged by gravity in the direction of the projecting portion.
