Self-pressurizing liquid nitrogen container is a new type of liquid nitrogen storage equipment, which is often used for liquid replenishment and turnover transportation of liquid nitrogen biological containers. It uses a small amount of liquid nitrogen in the tank to vaporize and generate pressure, so that the container can automatically discharge liquid nitrogen. It is widely used, especially in scientific research, medical care and animal husbandry, and has many advantages over traditional liquid nitrogen tanks. Next, I will introduce it to you in detail:
1. High-quality materials: Made of high-quality stainless steel, it is resistant to low temperature and corrosion, has good vacuum and thermal insulation properties, and can effectively avoid liquid ammonia evaporation.
2. Intelligent control system: It adopts advanced pressure control system and intelligent control system, equipped with booster valve, drain valve, vent valve, pressure gauge and other components, which is convenient and simple to operate, and increases the safety of laboratory work.
3. Continuous pressurization and continuous discharge: The tank can be continuously pressurized. When the pressure reaches 0.05Mpa, continuous and uninterrupted discharge can be achieved, and the infusion efficiency is high.
4. Double safety automatic valve: equipped with double safety automatic control valve, when the pressure reaches 0.09Mpa, the safety valve will automatically open, which is designed to prevent the internal pressure of the container from being too high, providing double protection, making liquid nitrogen filling more worry-free.
5. Easy to move: mobile casters are installed at the bottom of the tank, with high load-bearing capacity, which can be moved at will, making it more convenient and quick to replenish liquid nitrogen.
The above advantages and features jointly ensure the safety and efficiency of the liquid nitrogen supply tank in use, which is particularly suitable for laboratories and scientific research environments that require continuous liquid nitrogen replenishment.

This is chemical setting Furan based chemical resistant mortar which is combination of Liquid and Powder, when mixed in proper proportion from workable mortar which after setting and curing give of liquid and give black highly cross linked composites. Furan When set and cured is resistant to highly corrosive acids, alkalis and to powerful organic solvents such as ketones, Aromatic and Chlorinated solvents. It has extreme resistant to Acidic & alkalis, Salts, Greases and Detergents. It resists to Organic & Inorganic acids at their boiling temperature. It is suitable against mild chlorine Gas (dry) phosphorous trichloride, pyridine at room temperature. Furan is especially useful where resistance to mixed media such as aqueous acids /alkalis and organic solvents is needed in chemical plant process and waste streams. Carbon filled Furan is used against corrosive effect of hydrofluoric acid & its salts. PREPARATION OF FURANE MORTAR : Mortar consist of Furan solution and Furan powder. The average mixing ratio necessary to obtain mortar with good working consistency is 1 part by weight Solution & 3 part by weight powder. The ratio will vary slightly depending on temperature and working conditions.Stir the liquid thoroughly before using. Place liquid in a suitable shallow mixing pan. Add powder by weight in the solution mix thoroughly and rapidly until all lumps are dispersed and the mortar is completely homogenous. Spread out the mortar in a thin layer, not more than ¾ thick, to dissipate the heat of reaction and lengthen the working life. Batch size can be varied depending upon the temperature and the speed with which the masons are working. Very large batches will become stiff quite rapidly. Make sure that all the Furan Motrar is used from the pan before another batch is mixed.When working at temperature above 40 C, very small batches not more than 2 Kgs, should be prepared. When working at temperature below 15C the liquid should be kept warm.
