This is because the laboratory liquid nitrogen tank has such advantages. It is made of aviation aluminum, which has strong hardness, light weight, long-term durability and no deformation; large-diameter design facilitates sample pickup and placement; large capacity, stable and safe storage of samples; multi-layer insulation Vacuum design effectively reduces the volatilization of liquid nitrogen; it can meet the different needs of different workers.
Although, there are ways to use laboratory liquid nitrogen tanks.
1. Before use
It should be placed in a well-ventilated room, away from fire sources, electrical equipment, moisture-proof, and shaded;
Avoid storing in places where the temperature is too high or too low, and the humidity is too high or too low;
Check the sealing of the liquid nitrogen tank to see if there is air leakage. If there is any abnormality, contact after-sales service in time;
2. When using
Use caution when adding liquid nitrogen.
New jars should be filled slowly and pre-cooled to prevent the liner from cooling too quickly and reducing its service life;
When filling liquid nitrogen, do not pour liquid nitrogen on the vacuum exhaust port to avoid a decrease in vacuum degree;
The neck plug is made of thermal insulation material, which can not only prevent the evaporation of liquid nitrogen, but also play a role in fixing the lifting cylinder;
Check frequently. If frost is found on the surface of the tank, stop using it;
3.After use
Liquid nitrogen tanks should be placed on a stable and flat ground, away from direct sunlight and high temperature environments;
When not in use for a long time, it should be cleaned and stored to prevent sample residue from corroding the tank wall and affecting the service life;
It is recommended to place it in a well-ventilated area and regularly check the insulation performance of the tank;
