Description
Technical Field
The utility model relates to a freeze and deposit container for liquid nitrogen container belongs to cold-stored container technical field that preserves.
Background
The cryopreservation of biological specimens by using a liquid nitrogen tank is a commonly used technical means in clinical and experimental fields, and the liquid nitrogen preservation method is also called as an ultra-low temperature preservation method. Mainly utilizes the principle that the metabolism of microorganisms and cells tends to stop at the low temperature lower than-130 ℃, and effectively preserves in liquid nitrogen at the ultralow temperature of-196 ℃. The method is simple and efficient.
Among the prior art, in order to practice thrift the quantity of liquid nitrogen and transport the convenience of freezing sample, often use the portable liquid nitrogen container of small-bore to preserve the sample, the sample is placed in preserving the box, and preserving the box and placing in the liquid nitrogen container because the liquid nitrogen container takes place to rock easily in transporting the in-process for wherein the sample in preserving the box takes place to mix together easily, and is difficult for the separation. In addition, the efficiency of taking out and putting in the specimen of the existing preservation box is not high, and the specimens need to be taken out and put one by one. And each storage grid is integrated in the storage box, so that the storage box is not easy to clean after long-term use.
SUMMERY OF THE UTILITY MODEL
In order to improve the efficiency of getting of cold-stored sample, be convenient for deposit the washing change of net simultaneously, the utility model provides a freeze and deposit the container for liquid nitrogen container, concrete technical scheme as follows.
A freezing container for liquid nitrogen container is characterized by comprising a cylindrical part, a grid frame and a cover body,
the cylindrical part comprises a cylindrical side wall and a bottom plate, the top of the cylindrical side wall is open, and the cylindrical side wall is provided with a vertical opening along the height direction;
the cover body comprises a cap and a shielding part positioned at the lower edge of the cap, the cap is hinged with the top of the side wall of the cylinder, and when the cap covers the top of the cylinder part, the shielding part covers the vertical opening;
the grid frame is of a multi-layer structure, and each layer is provided with a plurality of grids.
By adopting the technical scheme, the grid framework with the multilayer structure can be put in from the top of the cylindrical part, so that all samples can be properly placed at one time, and the samples can be taken out in two modes, wherein one mode is to take out the grid framework from the top of the cylindrical part at one time to realize efficient taking out, the other mode is to take out a given sample from a vertical opening after opening the cover body when only individual samples need to be taken out, so that personalized taking out is realized, and the arrangement not only improves the sample taking and placing efficiency, but also considers the particularity of the individual samples. In addition, the grid frame and the cylindrical part are separately and independently arranged, so that the cleaning and the replacement of the grid frame become very simple.
Further, the top of cap still is provided with the peg. The peg can hang in the entrance of liquid nitrogen container, conveniently takes out the cryopreservation container from the liquid nitrogen container.
Further, the shielding part is a curved plate adapted to the side wall of the cylinder.
Furthermore, a plurality of through holes are formed in the side wall of the cylinder at intervals in the height direction. When the freezing container is placed in the liquid nitrogen tank, liquid nitrogen can enter the inner space of the side wall of the cylinder through the through hole, and the specimen can be ensured to be in the liquid nitrogen environment.
Furthermore, a lug with a through hole is arranged on the side wall of the cylinder, and a lug with a through hole is correspondingly arranged on the shielding part. When the cover body is in a closed state, the cover body can be prevented from being opened accidentally in the liquid nitrogen tank by means of a bolt or a steel wire penetrating through the two lugs.
Further, the freezing container is made of a metal material, and stainless steel is preferable.
The utility model discloses a set up multilayer structure's net grillwork in cylindric portion, make full use of liquid nitrogen pot inner space, promoted the whole of sample and got and put efficiency, taken into account the individualized time of taking out of individual sample moreover, enlarged the application scope of cryopreserving the container. Meanwhile, the grid frame which can be taken out is convenient for integral cleaning and replacement, and is beneficial to the long-term use of the whole freezing storage container.
