Description

Cryopreservation tube preservation rack for liquid nitrogen tank

technical field

The utility model relates to a storage rack for cryopreservation tubes for liquid nitrogen tanks.

Background technique

Preserving biological samples in liquid nitrogen can prevent the protein, RNA and DNA in the sample from degrading for a long time. Therefore, this preservation method is widely used in the research of biology, medicine, animal husbandry, veterinary medicine and other disciplines Sample preservation work in . At present, the main method of storing samples in liquid nitrogen is to put the cryopreservation tube containing the sample into a metal strainer or a gauze bag, and then put the metal strainer or gauze bag into a liquid nitrogen tank. Storing samples with the above method is likely to cause confusion of cryotubes, floating of cryotubes, difficulty in seeing labels on tubes, inability to fully save space, and difficulty in taking separate samples.

The current related patent "A Cryopreservation Tube Basket for Liquid Nitrogen Tank" (201320469827.8) consists of a handle, a connecting rod, a basket cover, a basket frame, a cryopreservation tube fixing hole, and a base. The handle is connected with one end of the connecting rod, the basket cover is set on the connecting rod, the other end of the connecting rod is installed on the basket frame and the base, and the basket frame is provided with a fixing hole for the cryopreservation tube. This patent overcomes some of the above shortcomings, but does not solve the problems of insufficient space saving and difficulty in separate sampling. The patent has a large volume and cannot be placed in a liquid nitrogen tank with a small diameter; due to the long distance between the cryotubes, it wastes the space in the liquid nitrogen; its "lifting blue cover" is not fixed On the "connecting rod", it is easy to cause the cryopreservation tube to fall off during the storage and sampling process; the "lifting blue cover" is a whole, which is not conducive to the storage and retrieval of a single cryopreservation tube.

Utility model content

The purpose of the utility model is to overcome the above-mentioned shortcomings, and provide a cryopreservation tube rack for liquid nitrogen tanks that is not easy to confuse samples, ensures that the cryopreservation tubes sink, is easy to see the labels on the tubes, fully saves space, and is easy to sample separately.

The utility model provides a storage rack for cryopreservation tubes for liquid nitrogen tanks. Hole (6), base tube hole (7), rod inner chamber (8), buckle shaft (9) and spring (10). The frame body and the base are fixed on the lifting rod, and the lifting rod is provided with buckles and rope holes, the frame body has a frame body tube hole, the base has a base tube hole, and the base tube hole bottom is closed.

The utility model not only overcomes the disadvantages of conventional sampling, but also solves the defects of similar patents. The "lifting rod" of the utility model is made of metal material, and the metal with relatively high density prevents the frozen storage tube from floating up and causing confusion; after storage, only a small part of the surface of the frozen storage tube is covered by the frame body, and the tube body is easy to see and the label on the tube cover; the "honeycomb" tube hole design makes the distance between the cryotubes almost at the minimum, which fully saves the precious space in the liquid nitrogen tank; only 6 cryotubes are placed on each tube rack , so that it can be stored in a liquid nitrogen tank with a narrow mouth; each cryotube is individually fixed by the "buckles" on the "frame tube hole", "base tube hole" and "lift rod", so that it will not It also facilitates access to individual cryovials.

Description of drawings

The above and other advantages of the present utility model will become clearer by describing exemplary embodiments of the present utility model in more detail with reference to the accompanying drawings, in which:

Fig. 1 is the front view of a cryopreservation tube preservation rack for a liquid nitrogen tank of the present utility model;

Fig. 2 is a cross-section of a lifting rod and a buckle of a cryotube preservation rack for a liquid nitrogen tank of the present invention.

Detailed ways

Hereinafter, the invention will now be described more fully with reference to the accompanying drawings, in which various embodiments are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Referring to accompanying drawings 1 and 2, the utility model provides a storage rack for cryopreservation tubes for liquid nitrogen tanks, which consists of a lifting rod (1), a rope hole (2), a buckle (3), a frame body (4), and a base (5), frame body pipe hole (6), base pipe hole (7), rod inner cavity (8), buckle shaft (9) and spring (10) form. The frame body and the base are fixed on the lifting rod, and the lifting rod is provided with buckles and rope holes, the frame body has a frame body tube hole, the base has a base tube hole, and the base tube hole bottom is closed.

When storing the cryopreservation tube, you only need to insert the cryopreservation tube into the "tube hole of the frame body" until the "tube hole of the base", at this time, the cryopreservation tube will be fixed by the "snap". When sampling, just press the "buckle" and pull out the freezing tube.

The utility model not only overcomes the disadvantages of conventional storage and retrieval of samples in liquid nitrogen tanks, but also solves the defects of similar patents. The "lifting rod" of the utility model is made of metal material, and the metal with relatively high density prevents the frozen storage tube from floating up and causing confusion; after storage, only a small part of the surface of the frozen storage tube is covered by the frame body, and the tube body is easy to see and the label on the tube cover; the "honeycomb" tube hole design makes the distance between the cryotubes almost at the minimum, which fully saves the precious space in the liquid nitrogen tank; each cryotube is individually framed by the tube hole , the base tube hole and the single "buckle" on the handle, so that it will not fall off, and it is also convenient for sampling a single cryotube.
