Abstract:

A shipper for safely transporting materials, particularly materials which must be precooled and maintained within a predetermined temperature for the time period while in transport, is provided. The shipper has a vessel for receiving and containing the sample material. The vessel has a contiguous wall defining a vessel cavity and a port for receiving the precooled material. A lid sealably engages with the port, the lid having an inert surface adjacent to the vessel cavity. A precooled refrigerant removably jackets the vessel to maintain the precooled material within a predetermined temperature range for a given period of time. A primary safeguard assembly for enclosing the jacketed vessel comprises a receptacle having a contiguous wall defining an opening and a receptacle cavity for receiving the refrigerant-jacketed vessel. A cover seals the opening of the receptacle and a sorbent is disposed between the vessel and the receptacle wall. A secondary safeguard assembly encloses the primary safeguard assembly.
