NARROW TUBE FOR FREEZE PRESERVATION OF BIOLOGICAL SPECIMEN, FREEZE PRESERVATION METHOD FOR BIOLOGICAL SPECIMEN AND METHOD FOR MELTING AFTER FREEZE PRESERVATION
PROBLEM TO BE SOLVED: To establish a freeze preservation technique of a biological specimen, keeping the simplicity of conventional technique, to perform the freeze preservation of a biological specimen of an animal in a narrow tube such as a straw, carry out the melting and dilution of the biological specimen in the narrow tube and keep high survival ratio of the biological specimen. SOLUTION: The narrow tube for freeze preservation comprises the freeze preservation of a vitrifying preservation liquid containing a biological specimen of an animal and a dilution liquid, the melting of the preserved specimen and the transplantation of the biological specimen to an animal. The dilution liquid 5 is filled from one end of the narrow tube body 2 to the other end in frozen state, and a linear supporting tool 3 holding the vitrifying preservation liquid 4 containing the biological specimen on the tip end is placed in the narrow tube body 2 in a manner to place the tip end of the linear supporting tool 3 adjacent to the end face of the frozen layer of the diluting liquid 5.
