[0002] Rabbit stem cell technology refers to the technology of using stem cells in rabbits for research and application. Stem cells are a type of pluripotent cells with self-renewal ability. Among them, rabbit stem cells are widely used in scientific research. After rabbit stem cells are collected into storage tubes, they need to be stored at low temperature.

[0003] At present, the Chinese utility model patent announced as CN210538466U discloses an experimental storage device for rabbit stem cells, which is provided with a nested box. A nested cavity is opened in the nested box. Sliding grooves are opened on the left and right end faces of the nested box. A limiting piece is installed at the end position of the sliding groove. A limiting column is provided at one end of the limiting piece. A storage tray is slidably connected in the nested cavity. A number of storage cavities for placing storage tubes are opened on the top end face of the storage tray. Sliding blocks are provided at the edges of the left and right ends of the storage tray. A clamping groove is opened on the side end face of the sliding block. Positioning columns are provided at the four corners at the top of the nested box. Positioning holes are opened at the four corners at the bottom of the nested box. In this experimental storage device for rabbit stem cells, by setting the storage tray in the nested box, the storage tray can be pulled out from the nested box, which is convenient for storing or taking out the storage tubes containing rabbit stem cells.

[0004] When this patent is used, the rabbit stem cell tube can be put into the storage tray. However, the storage tray and the external nested box are not hermetically set, and external pollutants are likely to enter the storage container, which will affect the purity of the stored rabbit stem cells. Content of the Utility Model
