In the process of cryopreservation of existing storage test tubes, when the temperature drops, the stem cell liquid stored in the test tube is often cooled gradually from the outer surface of the test tube to the inside, which results in a long waiting time for the entire liquid in the test tube to completely reach the preservation temperature. It is difficult to achieve the effect of rapid cryopreservation and is not convenient for the staff to use.
[0003] The prior art patent CN217136615U discloses a test tube for cryopreservation of stem cells, including a tube body. Both ends of the tube body are sleeved with tube caps.

By the foregoing solution, the technical problem that there is a certain dead angle between the tube body 103 and the tube orifice in the above structure, which is likely to cause incomplete subsequent cleaning and thus affect the quality of stem cells, is solved.
[0028] For this specific embodiment, the outer side of the tube cap 101 has a plurality of grooves 104. Sealing rings 105 are provided inside both the tube cap 101 and the bottom cap 102. Inner threads 111 are provided on the inner sides of both the tube cap 101 and the bottom cap 102. External threads 110 are provided at both ends of the tube body 103. The tube cap 101 is threadedly connected to the tube body 103 and sleeved on one end of the tube body 103. The bottom cap 102 is threadedly connected to the tube body 103 and sleeved on the other end of the tube body 103, and the external thread 110 is located at the inner thread 111. The sealing ring 105 abuts against the tube body 103. The setting of the sealing ring 105 can achieve a sealing effect. By providing the external thread 110 on the outer side of the tube body 103, and setting the tube cap 101 into a sleeve structure and providing an inner thread 111 on its inner wall, a flat and dead-angle-free space is formed inside the tube body 103, which is convenient for subsequent cleaning, thereby effectively ensuring the quality of stem cells.
