Problems solved by technology

[0003] However, the existing devices for storing biological samples through liquid nitrogen require the staff to wear protective gear and take the biological samples directly by hand. Due to the extremely low temperature of liquid nitrogen, it is very easy to frostbite the hands of the staff. ; In addition, in the process of storing and taking biological samples in the existing cryopreservation device, due to the lack of a sealing device, it is very easy to cause the leakage of liquid nitrogen, which affects the freezing effect of the device

Description

technical field [0001] The invention relates to the technical field of biological sample preservation equipment, in particular to a cryopreservation device for biological samples that is convenient for access. Background technique [0002] Biological samples are the basis of medical research, and their quality largely determines the accuracy and reliability of research results. Under normal conditions, there is oxygen in the air, and the microorganisms in the biological sample will grow and reproduce in contact with oxygen, and the vacuum packaging can effectively prevent the microorganisms from contacting with oxygen and prevent the growth of microorganisms. Cryopreservation is a commonly used method of biological sample preservation, and biological samples are cryopreserved through liquid nitrogen tanks. [0003] However, the existing devices for storing biological samples through liquid nitrogen require the staff to wear protective gear and take the biological samples di...
