Embodiment Construction
[0017] The present invention will be further described below in conjunction with the examples, but the present invention is not limited to the following examples.
[0018] The liquid nitrogen tank separation and lifting type cryopreservation tube storage device described in this example, as attached figure 1 And attached figure 2 As shown, it includes a cylindrical handle 10 composed of horizontally stacked handle pieces 11, and the cross-section of the handle pieces 11 is an arc-shaped cut surface that is wrapped sequentially. The arc-shaped section is more stable than the flat section, and the interlocking of the arc-shaped sections makes the superposition of the handle pieces more stable without too much slippage and deviation.
[0019] as attached figure 1 As shown, the basket frame 20 is composed of a storage layer 21 that increases sequentially from the top to the bottom. The storage layer 21 adopts a cylindrical appearance design, which is consistent with the prior a...

The invention discloses a separate lifting type cryopreservation pipe storage device for a liquid nitrogen tank. The device comprises a handle and a basket frame connected with the lower part of the handle, wherein the basket frame is formed by sequentially arranging multiple storage layers from top to bottom; each storage layer is connected with one handle piece; the handle is formed by transversely stacking the handle pieces; the section of the handle formed by stacking the handle pieces is round; contact surfaces of the handle pieces are arc-shaped surfaces; bottom surfaces of the storage layers are sequentially enlarged from top to bottom; and gradients are set for lengths of upper tails of the handle pieces. With the design, the technology for independently taking cryopreservation pipes stored in the different storage layers can be realized, and the problem that target samples cannot be taken out in a targeted manner for existing cryopreservation pipe storage devices is well solved.
Description
technical field [0001] The invention relates to the technical field of storage devices for cryopreservation tubes, in particular to a storage device for cryopreservation tubes of a separate lifting type for liquid nitrogen tanks. Background technique [0002] Cryopreservation tubes are important tools for preserving biological specimens and experimental samples, and can be used for low-temperature transportation and storage of biological materials. At present, liquid nitrogen is often used as a low-temperature refrigerant. The temperature of liquid nitrogen is very low, and the cooling speed is 30 times faster than that of ordinary freezing methods. It can preserve cells and other biological tissue samples for a long time. In the prior art, the cryotubes containing the specimens are usually stored in liquid nitrogen tanks for transportation and storage, and the cryotube storage device is usually placed in the liquid nitrogen tank. The cooperative use of the cryotube storage ...
