ABSTRACT:
A container for cooling, preserving and safely transporting a biological specimen includes a thermally insulating over-all container having as contents a container for ice, a container for the specimen including an isothermal metal cup, and a thermally insulating sheet interposed between the specimen container and the ice, the over-all container and the insulating sheet having thermal constants chosen to control the cooling rate, preferably to approximately one to three minutes per degree Centigrade, and to achieve a steady state temperature of the specimen near, but above freezing, preferably in the range of 4.degree. C. to 10.degree. C.
The method of the invention includes the steps of packing biological specimens just after they are obtained into a specimen container and placing the specimen container near ice in an over-all insulating container, with a thermally insulating sheet between the ice and the specimen container, the thermal constants being chosen to cool down the specimen at an optimum cooling rate and to achieve an optimum steady state temperature for the specimen.
