Description

Technical Field

[0001] The utility model belongs to the field of cryopreservation liquid, in particular to a cryopreservation liquid temperature control and temperature measurement device. Background Art

[0002] Cryopreservatives are solutions or liquid media specifically designed to preserve biological specimens such as cells, tissues, serum, etc. They are designed to freeze or refrigerate biological specimens at low temperatures to maintain their activity, stability, and availability for future use or analysis.

[0003] Freshly prepared cryopreservation solution will generate a large amount of heat. Before collecting cells in the cell cryopreservation experiment, the cell cryopreservation solution needs to be pre-cooled in advance to ensure that the temperature of the cell cryopreservation solution is appropriate when the cells are cryopreserved, thereby avoiding cell death due to excessively high temperature. The 4°C pre-cooling temperature of the refrigerator in the prior art is not stable enough, which is not only inconvenient for real-time monitoring of the sample tube temperature, but also difficult to adjust the temperature in the refrigerator according to the situation. When a large number of cells are frozen, the cryopreservation solution is kept at room temperature for a long time, which may cause temperature rise and affect the cell state. In addition, when the sample tubes containing the cryopreservation solution are placed in the refrigerator, they are often directly stuck in the placement hole, and when they are taken out, they need to be taken out by a buckling method, which is inconvenient.
