Description
Technical field
This utility model belongs to chemical storage apparatus field, is specifically related to a kind of portable Liquid nitrogen storage tank.
Background technology
Along with developing rapidly of molecular biology, the test relating to RNA is required to from tissue samples extract RNA, and
RNA is the most degradable, and its extraction must operate under extremely low temperature, extracts RNA the most voluntarily and typically adopts
By liquid nitrogen grinding, will be continuously added into liquid nitrogen after tissue samples puts into mortar in mortar, this allows for sample and maintains extremely low
At a temperature of to suppress the activity of digestive enzyme, owing to liquid nitrogen belongs to hazardous chemical, need to seal and preserve, existing liquid nitrogen tank skin
Layer is thicker, and weight and volume is all not suitable for laboratory and uses, and the testing crew extraction to RNA for convenience reduces the one-tenth of test
This, alleviate the working strength of testing crew, it is necessary to develop a kind of portable Liquid nitrogen storage tank.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of simple in construction, easy to use,
The portable Liquid nitrogen storage tank that good seal, price are low.
The purpose of this utility model is achieved in that a kind of portable Liquid nitrogen storage tank, and it includes tank body and seals lid,
Described tank body is cylindrical, and the right side on described tank body top is provided with fixed plate A, and the left side on described tank body top is arranged
Having fixed plate B, the middle part of described tank body upper surface to be provided with seal groove, the left side of described tank body lower part is provided with outlet,
Described outlet connects control valve, and the described right side sealing lid is provided with fixed plate C, and the described left side sealing lid is arranged
There is fixed plate D.
It is provided with sealing ring in described seal groove.
Described fixed plate A and the center of fixed plate B are provided with screwed hole.
Described fixed plate C and the center of fixed plate D are provided with unthreaded hole.
Described control valve connects remote control unit.
The beneficial effects of the utility model: this utility model is by using tank body, fixed plate A, fixed plate B, exporting, control
Valve, seal groove, sealing lid, fixed plate C, fixed plate D constitute a kind of portable Liquid nitrogen storage tank, have simple in construction, use
The advantage that convenience, good seal, price are low；It is provided with bolt in this utility model fixed plate C in use and fixed plate D, tightens
Tank body can be sealed firmly by bolt, not only reduces the leakage of liquid nitrogen, also improves the safety coefficient of tank body, it is ensured that test
The safety of personnel；It is provided with sealing ring, it is ensured that sealing effectiveness in seal groove of the present utility model；Total, this utility model has
Have simple in construction, the advantage that easy to use, good seal, price are low.
