BIOLOGICAL CELL FREEZING/PRESERVATION INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2023/132279
Kind Code:
A1
Abstract:
This biological cell freezing/preservation instrument 1 is provided with: four bottomed tubes 3 (3a, 3b, 3c, 3d); a cane 2 provided with holding units 11, 12, 13, 14 for the bottomed tubes; and a plurality of biological cell freezing/preservation tools 4. The cane 2 holds the four bottomed tubes in series at approximately regular intervals. Each of the biological cell freezing/preservation tools 4 is configured such that, when a tubular member 50 is attached to a rod-shaped main body part 41, the entire length is shorter than a distance L1 between outer bottom surfaces of adjacent bottomed tubes. An upper end opening 33 of each of the bottomed tubes is an inclined opening that descends toward the front end of a cane main body part 21. Each of the biological cell freezing/preservation tools 4 is also configured such that, when each of the biological cell freezing/preservation tools 4 is placed in the bottomed tube with the tubular member 50 arranged downward, the upper part of the rod-like main body part 41 is exposed.
