The liquid nitrogen container, also known as liquid nitrogen tank, liquid nitrogen bottle or Dewar bottle, may look like an ordinary storage tank, but it is actually made of aviation aluminum or stainless steel. This material has excellent heat insulation performance and high vacuum characteristics, which can effectively maintain the low temperature environment in the box and reduce the evaporation of liquid nitrogen. This can make better use of the characteristics of liquid nitrogen and protect its biological activity.
Liquid nitrogen tank
Liquid nitrogen storage tanks are widely used. They are often used in scientific research, medicine, biological freezing and other fields. For example, in the field of biotechnology, liquid nitrogen containers are widely used to store biological samples, cells, tissues and even eggs and embryos. Using these liquid nitrogen containers can not only prolong the storage time of samples and maintain their activity, but also better protect samples from external environment. Because of this, liquid nitrogen container has become an indispensable part of modern science and technology and medical field.
When using liquid nitrogen containers, we need to pay attention to some matters and carry out regular maintenance.
1. Before use, check whether there is a depression outside the tank and whether the vacuum exhaust port is intact;
2. The liquid nitrogen tank is only used for filling liquid nitrogen, and other liquids or mixed storage are not allowed;
3. The handling and storage of liquid nitrogen containers also need to be careful to avoid falling and collision;
4. When storing liquid nitrogen for a long time, it is necessary to replenish liquid nitrogen regularly, which is generally reasonable when the residual amount of liquid nitrogen is 1/3;
5. Clean the internal and external surfaces of the liquid nitrogen tank regularly to avoid the accumulation of dust and impurities. Cleaning with detergent and soft cloth can remove stains and deposits.
