Technical Field

[0001] This utility model relates to a cryopreservation box and its storage rack. Background Technology

[0002] Cryopreservation boxes are containers used for cryogenic storage of biological samples and are the most basic and crucial storage tools in biological experiments. The core function of cryopreservation boxes is to safely, systematically, and efficiently store biological samples under low-temperature conditions for extended periods, protecting them from temperature fluctuations and contamination. They are widely used in laboratories, medical fields, and biotechnology, for samples such as cells, tissues, bacteria, DNA, RNA, serum, and sperm, eggs, and embryos.

[0003] However, when the cryopreservation box is removed from the liquid nitrogen tank, liquid nitrogen remains inside, requiring manual handling. Therefore, it is necessary to improve the cryopreservation box to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a cryopreservation box and its storage rack. The cryopreservation box helps to guide liquid nitrogen out of the box, while the storage rack facilitates the placement of the cryopreservation box.

[0013] Compared with the prior art, the present invention has the following advantages: 1. Drain holes are made at the bottom of the inner chamber to allow liquid nitrogen to flow from the bottom of the chamber into the outer chamber, and then the liquid nitrogen is discharged through the drain trough of the outer chamber to prevent liquid nitrogen from remaining in the cryopreservation box.

[0014] 2. The storage rack facilitates the placement of cryopreservation boxes within the rack, which is then placed inside the liquid nitrogen tank. The side wall of the rack features perforations that allow liquid nitrogen from the cryopreservation boxes to flow out of the storage cavity. A baffle bar helps prevent the cryopreservation boxes from detaching from the storage cavity, and pulling the baffle bar facilitates their removal. Attached Figure Description

Drainage channels 12 are longitudinally arranged on both sides of the outer box body at the lower end (lower end) of the arched bottom plate. Multiple inner boxes are arranged side by side along the longitudinal direction inside the outer box body. The inner boxes are divided into multiple chambers 21 by partitions 22 at intervals along the transverse direction. Drainage holes 23 are provided on the bottom plate of each chamber. Liquid nitrogen in the chamber can be drained through the drainage holes and then discharged in a concentrated manner through the liquid dispensing channel, which helps to prevent liquid nitrogen from remaining in the cryopreservation box when it is removed from the liquid nitrogen tank.

[0018] In this embodiment, to reduce the adhesion of liquid nitrogen to the bottom surface of the cryopreservation box after discharge, longitudinal flanges 13 are provided on the lower ends of both sides of the outer box. Lifting portions 24 are provided on the upper ends of both sides of the inner box. The height of the lifting portions is less than the height of the longitudinal flanges, which facilitates the removal of the inner box from the outer box and also makes it convenient to stack the cryopreservation boxes vertically during storage.

[0019] In this embodiment, the front end face of the outer box is provided with a pull-out part 14 and a lifting ring, so as to facilitate the freezing box being pulled out from the storage cavity of the storage rack.
