Description

Technical Field

[0001] The utility model belongs to the technical field of sample storage, and more specifically, particularly relates to a sample storage device for detecting small molecules in animal tissues and blood. Background Art

[0002] For animal experiments, animal sampling is indispensable. It is a critical step in our animal experiments: it directly affects whether an experiment can obtain accurate data and publish high-quality articles. Therefore, sampling and storage of samples are very important. Liquid nitrogen storage is a common low-temperature storage method. The temperature of liquid nitrogen is extremely low, reaching -196°, which can effectively prevent the natural aging and apoptosis of cells and tissues, thereby ensuring the integrity and stability of samples over a long period of time.

[0003] Based on the above, the inventors have found the following problems: current sample storage devices usually use a liquid nitrogen tank to store samples at low temperatures, but when the liquid nitrogen tank is opened to take out the sample stored inside for testing, the liquid nitrogen will be exposed to the air, and the liquid nitrogen will quickly vaporize and lose, resulting in a large loss of liquid nitrogen, waste, and inconvenience in use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a sample storage device for animal tissue and blood small molecule detection is provided, in order to achieve a purpose with greater practical value. Utility Model Content
