Abstract

The invention discloses a liquid nitrogen storage system for storing and fetching a single sample on a storage position in a liquid nitrogen tank. The system comprises the liquid nitrogen tank, wherein a sample storage assembly is arranged inside the liquid nitrogen tank. The system is scientific and reasonable in structure, and safe and convenient to use; the liquid nitrogen storage system is provided with the sample storage assembly, a plurality of samples can be conveniently stored in a groove at the top end of each large turntable, the large turntables can rotate independently under the action of a first bearing, and then the sample can be conveniently stored or fetched at a designated position of a designated large turntable according to the requirement of a user; and the whole selected sample working area is arranged on the storage position in the tank, the whole process is at the environment temperature consistent with the freezing environment temperature, namely about minus 185DEG C, therefore, repeated freezing and thawing of samples are thoroughly avoided, high requirements on safety and long-acting performance of biological samples in the accurate medical era are effectively guaranteed, the gap between traditional freezing storage racks is eliminated to save space, the available space of freezing is greatly expanded, and the storage capacity of the same space is maximized.

Description

technical field [0001] The invention relates to the technical field of biological cell sample storage, in particular to a liquid nitrogen storage system for single sample access at a storage position in a liquid nitrogen tank. Background technique [0002] Cells are the basic structural and functional units of organisms. It is known that all organisms except viruses are composed of cells. In medical treatment, it is often necessary to freeze and store cell samples to maintain the safety and long-term effectiveness of cell samples. The cell samples of ordinary cryopreservation equipment are stored by placing the cell samples in the cryopreservation box, and placing the cryopreservation box in the cryopreservation rack for freezing, which increases the occupied space. The box is taken out of the freezing tank to select a single cell sample, and the unnecessary samples are put back into the freezing shelf for freezing, which will cause the risk of repeated freezing and thawing ...
