Introduction to liquid nitrogen tank

 

 


Liquid nitrogen tank
 

        The liquid nitrogen biological container is mainly used for breeding livestock semen frozen storage (AL) and cryopreservation of human organs, skin, blood, cell , industrial cooling assembly ,cold treatment of metallic materials ,cryogenic  comminution , superconducting and other aspects .With the development of science and technology and the needs of industrial and agricultural production , it will be quickly spread and application , and show a bright future.

       Liquid nitrogen biological container has the characteristics of light weight, easy to carry and good refrigeration performance. The shell is made of high-strength aviation special rust-proof aluminum alloy, double-layer vacuum structure, ultra-adiabatic design, small evaporation and long liquid nitrogen storage time Widely used in animal husbandry, medical treatment, scientific research, storage of semen, embryos, bacteria, vaccines, skin, organs and other active materials as well as industrial, cryogenic treatment, molecular food , beauty freckle, cold therapy ,etc.

Classification of liquid nitrogen tanks
 


 ♦Liquid nitrogen storage tank (storage type): Liquid nitrogen is stored for a long time and is suitable for long-term preservation of active biological materials in a standing room. The conventional model has several buckets. The conventional model of liquid nitrogen tanks is usually equipped with three round buckets. The storage type liquid nitrogen tank can be used to place specimens, cells, etc. for cryopreservation.
 ♦Liquid nitrogen storage tank (transport type): Supported in the inner bladder, resistant to transportation and vibration, suitable for indoor stationary and long-distance transportation.

 ♦There is also a self-pressurized liquid nitrogen tank: it can not store anything else (except liquid nitrogen), the product structure is provided with liquid nitrogen vaporization self-pressurizing pipeline, using the heat outside the container to make a little liquid nitrogen vaporize to generate pressure, The liquid nitrogen is output and can be transported.


      •Classified by volume: storage liquid nitrogen containers from large to small: 2L, 3L, 5L, 6L, 10L, 15L, 20L, 30L, 35L
     •Transport and storage of two-purpose liquid nitrogen biological containers from large to small: 10L, 15L, 30L, 35L, 50L, 100L
     •Self-pressurized liquid nitrogen container: 50L, 100L, 175L, 200L, 300L, 500L
     •Classified according to different calibers: 35mm, 50mm, 80mm, 125mm, 500mm

  2.It has the corrosion resistance, low temperature resistance,the advantage can prevent frost crack and frost  collapse。
  3.The product is composed of two parts, upper cover and the lower cover ,the user can select lock for container storage sample preservation and management.



 





 

 

Use and Attention

 

 ♦The container can only be used for filling liquid nitrogen ,please not filling other liquid gas, in use is strictly prohibited during collision , so as not to damage the tank of high vacuum state. it is forbidden to use storage tank transportation tank . nitrogen transport and need to special transportation tank .prohibit use of sealing plug sealed tank mouth, in order to avoid liquid nitrogen to evaporate to form nitrogen increased pressure and accidents.
 
 ♦Pail operation
The use of pail, quickly fetching ,so as not reduce the storage of biological activity of samples, when the lifting tube into the container after, rapid cover on the plug ,to reduce the consumption of liquid nitrogen; lifting barrel out please be careful , not scratch neck tube wall.
 
 ♦Add liquid nitrogen                      
Please add the liquid nitrogen in a timely manner ,when the liquid nitrogen allowance is equal to the full capacity of the 1/3,should be added in a timely manner appropriate , so as not to reduce the biological activity of samples.
 
 ♦Air circulation
Although nitrogen is odorless and non-toxic gas, it's might cause indoor nitrogen content increased under a poor ventilation evaporation and the oxygen content would be decreased relatively that may affect user's healthy. Therefore, the storing place needs to enhance the ventilation and keep the air fresh.
 
 ♦Protective neck tube
The container has been used for a long time, the inner wall of the tube neck will frost, ice, please use the hot blowing machine(such as hair dryer)
 
 ♦Protective neck plug
The neck plug is made of polyurethane foam , in the process of use , please gently ,so as not to break the core plug.
 
 ♦Wash and dry
During use of container, the water will be slowly accumulate at internal bile and multiply bacteria and pollute the liquid nitrogen. That will cause considerable corrosion of the liner, also the proliferation of bacteria will reduce the sperm efficiency. Therefore, it is better to wash the container 1-2 times a year.






 

 


Washing method is as follows
 


1.Remove the pail from the container and allow it to stand for about two days. The high temperature in the container will rise to about 0℃.
2.Fill the inner tank with warm water at 40-50℃ and scrub it with cloth.
3.Rinse with water 2-3 times
4.Upside down container, make it dry, you can use natural and hot air drying methods. If the use of hot air drying, the temperature should be limited to 40-50℃ between the avoidance of more than 60℃ hot air.


 

 


 


Static liquid nitrogen daily evaporation test
 


♦The test environment temperature is 20±3℃, without the lifting tube, cover the neck plug.
♦The container was filled with liquid nitrogen more than 1/2 volume, static for 48 hours for the first weigh1.The test environment temperature is 20±3℃, without the lifting tube, cover the neck plug.
♦The container was filled with liquid nitrogen more than 1/2 volume, static for 48 hours for the first weighing A(g), the second weighing B(after 3 days), according to the following formula evaporation Q.

  Q= (A-B)/3 (g/day)
  If you need capacity (liters) said, with the following conversion:
  D=Q/808 (L/day)
