Abstract: A spirally ascending/descending cryogenic storage apparatus, comprising a cryogenic storage tank, the temperature in the cryogenic storage tank being continuously maintained at a certain deep cryogenic range. A driving component and a rotating storage rack are provided within the cryogenic storage tank. Multiple shelf boxes can be stored in the circumferential direction of the rotating storage rack. The driving component can drive the rotating storage rack to spirally ascent or spirally descent in the cryogenic storage tank. An access opening is provided on the cryogenic storage tank. The multiple shelf boxes can rotate to a position corresponding to the access opening with the movement of the rotating storage rack. The cryogenic storage tank is a liquid nitrogen tank. Liquid nitrogen is provided at the bottom part within the liquid nitrogen tank.

Abstract: A liquid nitrogen tank includes a tank, a storage rack and a drive component. The tank includes a tank cover, a tank body, a vacuum cavity layer and a heat-insulating cavity layer. The tank cover is disposed to cover on the tank body. An access door is provided on the tank body. A storage cavity is provided in the tank body. The heat-insulating cavity layer is provided on a periphery of the storage cavity. The vacuum cavity layer is provided on a periphery of the heat-insulating cavity layer. The storage rack is provided in the storage cavity. A plurality of cryopreservation tube racks are stored in the storage rack. The drive component can drive the storage rack to rotate and move up and down in the storage cavity, and can drive the plurality of cryopreservation tube racks to move to a position corresponding to the access door.

Abstract: A tube-array-type liquid nitrogen container includes a container body having a mouth; a tube array component received in the container body; and a top cap sealing the mouth from above. The top cap is rotatable in the mouth. The tube array component is composed of a plurality of holding tubes. The holding tube is opened at one end thereof, wherein the opening thereof faces the top cap. The top cap has at least one tube access passing therethrough. Each tube access is atop covered by a tube access cover. The tube-array-type liquid nitrogen container uses a tube-array component composed of the a plurality of holding tubes to store the freezing tubes, and is cooperated with the rotatable top cap and an external robotic arm, thereby improving space utilization and thermal insulation, effectively ensuring safety of the freezing tubes, and facilitating automatic storage of freezing tubes.
