Technical Field
The utility model relates to the technical field of cryopreservation tubes, in particular to a cryopreservation tube for a small amount of cells.
Background
Cell cryopreservation is a technology for placing cells in a low-temperature environment so as to reduce cell metabolism and achieve long-term storage, and is one of the main methods for cell preservation, and plays a role in cell seed preservation. In the process of freezing and preserving the cells, the cells are required to be collected firstly, then the cells are preserved at a low temperature by using a cell freezing tube, and the cells are taken out and heated when in use, so that the activity of the cells can be recovered again.
However, when the existing cell cryopreservation tube is stored in the cryopreservation instrument, if the periphery of the cell cryopreservation tube is not supported, the problem that the cylindrical tube body is easy to roll off can occur in the cryopreservation tube, and most of the existing cryopreservation tubes are in cylindrical shapes, so that when the cells to be cryopreserved are fewer, the use amount of the cryopreservation liquid can be increased by using the cylindrical cryopreservation tube.
Therefore, there is a need to provide a cryopreservation tube for a small amount of cells that solves the above technical problems.
Disclosure of utility model
In order to solve the technical problems that a freezing tube is easy to drop and the usage amount of freezing solution can be increased when the number of frozen cells is small in the prior art, the utility model is realized in the following way: a cryopreservation tube for a small amount of cells comprises a tube body and a tube cover mounted on the tube body;
The top of the pipe body is provided with threads, and the pipe cover is arranged on the pipe body through threads;
The bottom of the pipe body is conical;
Arc-shaped supporting legs are arranged at the bottom of the pipe body in a surrounding mode;
At least two circular bulges are arranged above the pipe body, and when the pipe body is transversely placed, the two circular bulges are positioned in the same plane.
Preferably, the cryopreservation tube further comprises a gasket;
The gasket is installed in the pipe cover, and when the pipe cover is connected with the pipe body, the gasket is attached to the top of the pipe body.
Preferably, the height of the circular protrusion is 0.3 mm-0.6 mm.
Preferably, the gasket is made of rubber.
Preferably, the material of the pipe body and the pipe cover is polypropylene.
Preferably, the surface of the tube body is provided with a marking groove.
By implementing the utility model, the technical problems that the freezing tube is easy to drop and the usage amount of freezing solution can be increased when the frozen cells are fewer in the prior art can be solved; according to the utility model, the bottom of the tube body is conical, the arc-shaped supporting legs are additionally arranged at the bottom of the tube body, and at least two circular protrusions are arranged above the tube body, so that the freezing tube is not easy to fall off, can be used for preserving a small amount of cells, saves the using amount of freezing solution, and increases the contact area of the cells.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples
In a specific embodiment, as shown in fig. 1, a freezing tube for a small amount of cells comprises a tube body 1 and a tube cover 2 mounted on the tube body 1, wherein the top of the tube body 1 is provided with threads, the tube cover 2 is mounted on the tube body 1 through threads, the bottom of the tube body 1 is conical, the bottom of the tube body 1 is provided with arc-shaped supporting legs 1-3 in a surrounding manner, at least two circular protrusions 1-2 are arranged above the tube body 1, when the tube body 1 is transversely placed, the two circular protrusions 1-2 are located in the same plane, in this embodiment, the tube body 1 can be vertically placed on a table surface due to the arc-shaped supporting legs 1-3 being arranged in a surrounding manner, at this time, a small amount of cells stored inside is placed in the conical bottom of the tube body 1, and the amount of frozen liquid to be added is smaller than the volume of frozen liquid to be added in the cylindrical shape, and the contact area of the frozen liquid and the cells can be increased. And because the two circular bulges 1-2 are positioned in the same plane, the pipe body 1 can be transversely placed on a table top and cannot fall off.
In a preferred embodiment, the freezing tube further comprises a gasket 2-1, the gasket 2-1 is installed in the tube cover 2, when the tube cover 2 is connected with the tube body 1, the gasket 2-1 is attached to the top of the tube body 1, and the gasket 2-1 is made of rubber, so that a better sealing effect can be provided.
In a preferred embodiment, the height of the circular protrusions 1-2 is 0.3 mm-0.6 mm, when the freezing tube is placed transversely, the two circular protrusions 1-2 are on the same plane, through the circular protrusions 1-2 in the embodiment, the upper part of the tube body 1 can be lifted, freezing solution in the freezing tube cannot flow out along the inner wall of the freezing tube, the two circular protrusions 1-2 can ensure that the freezing tube cannot roll, in the embodiment, the freezing tube in the embodiment can only roll on one side of the freezing tube due to the fact that the freezing tube can only roll on one side of the freezing tube due to the fact that the two circular protrusions 1-2 are arranged, and therefore the circular protrusions 1-2 can also be arranged around the tube body 1 in a plurality, and the intervals of the circular protrusions 1-2 are the same.
In a preferred embodiment, the material of the pipe body 1 and the pipe cover 2 is polypropylene, the chemical and temperature stability is strong, and the pipe body and the pipe cover can resist low temperature to minus 187 ℃ under the gas state environment of liquid nitrogen.
