Technical Field

The disclosure relates to the field of chemical storage equipment, in particular to a simple liquid nitrogen storage tank.

Background

With the rapid development of molecular biology, RNA experiments need to be carried out on RNA extracted from tissue samples, the RNA is easy to degrade at normal temperature, the extraction needs to be carried out at extremely low temperature, currently, the RNA is automatically extracted from laboratories and generally ground by liquid nitrogen, namely, after the tissue samples are put into a mortar, liquid nitrogen is continuously added into the mortar, so that the samples are maintained at extremely low temperature to inhibit the activity of degrading enzymes, the temperature of the liquid nitrogen at normal pressure is-196 ℃, and therefore, the physicochemical property of the liquid nitrogen at room temperature and normal temperature is extremely unstable and easy to volatilize, and in addition, due to the low temperature of the liquid nitrogen, human skin is frozen and damaged by directly contacting the liquid nitrogen for more than 2 seconds and cannot be reversed. Because liquid nitrogen belongs to dangerous chemicals, needs sealed the saving, and current liquid nitrogen container wall is thick, and weight and volume are all not fit for the laboratory and use, and traditional portable liquid nitrogen saves jar for high density material, and the quality is big, not well move, and the cost of manufacture is high, for the extraction of experimenter to RNA, reduces experimental cost, alleviates experimenter's working strength, is necessary to develop a portable liquid nitrogen and saves jar.

Disclosure of Invention

The purpose of the disclosure is to provide a simple liquid nitrogen storage tank, so as to achieve the effects of simplicity and economy.

In order to realize the purpose, the technical scheme is as follows:

The utility model provides a jar is preserved to simple and convenient liquid nitrogen, it includes box, case lid and centrifuge tube rack to preserve the jar, the inboard of box is equipped with the recess, the centrifuge tube rack inlays in the inboard recess of box, the case lid is located the top of box, the case lid downside is equipped with the boss, agrees with mutually with the recess of box upside, cloth has the centrifuge tube hole on the centrifuge tube rack, the material of box and case lid is heat preservation material that prevents frostbite.

The outside of box is equipped with anti-skidding setting.

The two sides of the outer side of the box body are provided with handles.

The anti-skid box body is formed by wrapping a layer of anti-skid rubber on the outer side of the box body.

The centrifuge tube frame is made of medium alloy steel or austenitic low-temperature steel.

And the upper magnet is arranged on the boss at the lower side of the box cover and is attached to the lower magnet arranged on the groove at the upper side of the box body.

The box body and the box cover are made of foam or closed-cell foam glass.

The beneficial effects of this disclosure are: the simple liquid nitrogen storage tank is simple in structure and only comprises a tank body, a tank cover and a centrifuge tube rack, and the tank body and the tank cover are made of anti-freezing heat-insulating materials, so that the simple liquid nitrogen storage tank has the advantages of simplicity in preparation and cold insulation; the centrifuge tube shelf is arranged in the box body, centrifuge tube holes are formed in the centrifuge tube shelf, centrifuge tubes with different sizes can be placed in the centrifuge tube shelf, and material samples can be conveniently stored; the upper portion of the box body of the liquid nitrogen storage tank is provided with a boss structure which is matched with a groove structure at the lower portion of the box cover, so that the liquid nitrogen storage tank has good sealing performance and can reduce volatilization of liquid nitrogen.

Wherein the outer side of the box body in the liquid nitrogen storage tank is provided with an anti-skid device which plays a role in preventing skidding when the storage tank is moved or taken.

The outside of box is equipped with the handle setting in the liquid nitrogen conservation jar, can be convenient for the transport of liquid nitrogen conservation jar.

The material of the centrifugal tube frame in the liquid nitrogen storage tank is medium alloy steel or austenite low-temperature steel, the two steel materials are ultralow temperature resistant materials, and good toughness can be kept in an ultralow temperature environment, so that the prepared centrifugal tube frame cannot deform when being at the temperature of liquid nitrogen-196 ℃, the centrifugal tube hole cannot shrink, and the service life of the liquid nitrogen storage tank is prolonged.

all be equipped with magnet on the boss of case lid downside of liquid nitrogen preservation jar and on the recess of box upside, and can laminate mutually, make like this and have better seal between case lid and the box, and magnet all inlays in boss and recess, so strengthened the seal of liquid nitrogen preservation jar more for be difficult for spilling when carrying liquid nitrogen preservation jar preserved liquid nitrogen and leak out.

The box body and the box cover in the liquid nitrogen storage tank are made of foam or closed-cell foam glass, the foam and the closed-cell foam glass are light in weight, have good cold-resistant and heat-insulating functions and are low in price, and therefore the liquid nitrogen storage tank prepared from the two materials has the advantages of cold-resistant and heat-insulating properties, lightness, simplicity and saving.
