Abstract
The utility model relates to a liquid nitrogen cryopreservation box. The liquid nitrogen cryopreservation box comprises a box body and a box cover, wherein the box cover covers the top of the box body; the box body is made of stainless steel or aluminum alloy; grids are arranged inside the box body; a row of nitrogen exhausting holes are formed in four corners of the bottom of the box body respectively. The liquid nitrogen cryopreservation box disclosed by the utility model adopts the stainless steel or the aluminum alloy so that the service life is long; meanwhile, the nitrogen exhausting holes and circular holes are formed in the bottom of the box body so that liquid nitrogen can rapidly leak out from the cryopreservation box.
Description
[technical field]
The utility model relates to a kind of refrigerating plant, is specifically related to a kind of liquid nitrogen cryopreservation box, belongs to the laboratory apparatus technical field.
[background technology]
The liquid nitrogen cryopreservation box is generally used for placing cryopreservation tube, and it is deposited in the liquid nitrogen container, thereby cryopreservation tube low temperature is preserved.
The liquid nitrogen cryopreservation box of prior art all adopts paper material, damaged distortion occurs easily after ultralow temperature, the long-term use.Simultaneously, existing liquid nitrogen cryopreservation box can't be discharged liquid nitrogen fast.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved liquid nitrogen cryopreservation box that has, to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the liquid nitrogen cryopreservation box that provides a kind of structural strength high, easy to use and safe is provided the purpose of this utility model.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of liquid nitrogen cryopreservation box, and it comprises box body and lid; Described box body is rectangular structure, and described lid is placed on the top of box body; Described box body is the box body of stainless steel or aluminum alloy material; In described box body, be provided with a grid; Four jiaos are respectively equipped with a denitrogen hole in the bottom of described box body.
Liquid nitrogen cryopreservation box of the present utility model further is set to: the bottom in described box body also is provided with some circular holes; Described circular hole number is preferably 2.
Compared with prior art, the utlity model has following beneficial effect: liquid nitrogen cryopreservation box of the present utility model adopts stainless steel or aluminum alloy material, thereby makes longer service life; Simultaneously, by offering denitrogen hole and circular hole in the box body bottom, spill fast from freezing storing box thereby be convenient to liquid nitrogen.
[description of drawings]
Fig. 1 is the schematic diagram of the box body of liquid nitrogen cryopreservation box of the present utility model.
Fig. 2 is the schematic diagram of the lid of liquid nitrogen cryopreservation box of the present utility model.
[specific embodiment]
See also shown in Figure of description 1 and the accompanying drawing 2, the utility model is a kind of liquid nitrogen cryopreservation box, and it is comprised of several parts such as box body 1 and lids 2.
Wherein, described lid 2 is placed on the top of box body 1, by described lid 2 is set, avoids cryopreservation tube in use because misoperation breaks away from the situation generation of freezing storing box.
Described box body 1 is rectangular structure, and it is the box body 1 of stainless steel or aluminum alloy material, thus the longer service life of this freezing storing box.
Be provided with a grid 3 in described box body 1, this grid 3 can be placed cryopreservation tube (not shown) with being divided into 5 * 8 little lattice 6 of square in the box body 1 in the little lattice 6 of square.
Four jiaos are respectively equipped with a denitrogen hole 4 in the bottom of described box body 1.And also be provided with 2 circular holes 5 in the bottom of described box body 1.By offering described denitrogen hole 4 and circular hole 5, spill fast from freezing storing box thereby be convenient to liquid nitrogen.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
