Description
Technical Field
The utility model relates to the technical field of low-temperature medical equipment, in particular to a multifunctional program cooling box.
Background
Cryopreservation refers to a technique for storing biological samples at low temperature (e.g., liquid nitrogen, ultra-low temperature refrigerator). Scientists have long demonstrated that biological cell samples can be stored in low temperature environments for long periods of time. However, directly placing the cells in a low-temperature environment can cause damage to the cells, such as ice crystals or solutes, and the damage is irreversible and can affect the activity of the cells after recovery. Scientists have found that adding cryoprotectants to cryopreserved samples, when stored directly in a low temperature environment, can reduce irreversible damage to cells from the low temperature environment, but does not achieve the desired effect. Further research shows that the programmed cooling of the cell sample added with the cryoprotectant can obviously reduce the damage of ice crystals or solute and improve the recovery survival rate of cells.
At present, an isopropanol program cooling box or a program cooling instrument is most commonly used for carrying out program cooling on a frozen sample, but isopropanol belongs to a toxic solvent and is extremely volatile, so that the environment is polluted and the personal safety of experimenters is threatened after long-term use; the program cooling instrument is expensive, and has a great risk to the personal safety of experimenters due to the characteristics of volatile liquid nitrogen and extremely low temperature.
