French Polynesia 35 liter liquid nitrogen dewar laboratory dewar

In laboratories and scientific research institutes, experimental samples and cells often need to be stored in a low-temperature environment for a long time. There are many cryogenic containers on the market, and laboratory liquid nitrogen tanks stand out and are entrusted with reuse.

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;

In short, the role of liquid nitrogen tanks in the laboratory is irreplaceable, but their correct use is crucial. During the operation, you must not only pay attention to the storage of the liquid nitrogen tank, but also the addition and correct use of liquid nitrogen to ensure the safety of staff and samples.
