Description

Technical Field

[0001] The utility model relates to the technical field of cell freezing, in particular to a cell freezing box with a protective structure. Background Art

[0002] Cell cryopreservation is one of the main methods of cell preservation. Using cryopreservation technology to store cells in liquid nitrogen at low temperatures can temporarily remove cells from the growth state and preserve their cell characteristics, so that the cells can be revived for experiments when needed. In addition, appropriately storing a certain amount of cells can prevent cell loss due to contamination of the cells being cultured or other unexpected events, thus playing a role in cell preservation. Cryopreservation tubes for cell cryopreservation are usually placed in cryopreservation boxes.
