Description

Technical Field

[0001] The utility model relates to the technical field of sample preservation, in particular to a sample preservation device for molecular biology. Background Art

[0002] Molecular biology is a science that studies the structure and function of biological macromolecules at the molecular level in order to clarify the essence of life phenomena. Its main research areas include protein systems, protein-nucleic acid systems, and protein-lipid systems. When conducting molecular biology research, it is sometimes necessary to go out for sampling. In order to maintain the biological activity of the samples, the samples need to be stored in low-temperature refrigeration containers.

[0003] For example, the Chinese utility model provides a "sample preservation device for molecular biology" with patent number: CN 209455255U, which solves the inconvenience of storing liquid samples in the prior art, including a box body, a box cover and a partition plate. The box body includes an inner layer and an outer layer of the box body, and a cavity structure is formed between the inner layer and the outer layer of the box body. A box cover is arranged on the upper part of the box body, a cold material port is opened on the upper part of the outer layer of the box body, and a cold material port plug is inserted into the cold material port. A plurality of partition plates are integrally arranged inside the inner layer of the box body, and the partition plates divide the internal space of the inner layer of the box body into a plurality of storage cavities, and an inner cover is arranged on the upper side of the storage cavity, and a sealing plug is arranged on the lower side of the inner cover, and a liquid bag is arranged inside the storage cavity. The utility model adds an inner cover on the upper side of each storage cavity to avoid contamination of other samples during sample placement, and a liquid bag is arranged on the inner side of the storage cavity to store liquid samples and prevent the samples from flowing out.

[0004] Although the above document solves the problem of sample preservation, it can only store a single sample, and the sealing structure on the top after the sample is stored is relatively simple. In addition, if the top cover shakes during carrying, the internal sample will leak, thus affecting the storage and carrying of the sample. Utility Model Content
