Hot Sale Liquid Nitrogen Container Liquid Nitrogen Dewars

 Liquid nitrogen dewar

Working principle
(1)The liquid nitrogen dewar consists of an inner container,an outer container ,a canister and a neck tube lingking two containers above. The strength durable inner container and outer container are made up of high strength aluminum alloy.
(2) The storage tank employs multi-layer thermal insulation material in high vacuum space between the inner and outer containers. Therefore it has excellent performance of deep freezing.
(3) The neck tube is made of reinforced glass plastic which has the lowest heat conduction coefficient, and for this reason it can control outside heat coming into the container from the neck tube to the minimum limit.



Product  structure:

A) Inner liner is made of high strength aluminum alloy, constructed with sturdy and durable.

B) Between the liner and the outer liner is a high vacuum, vacuum film with multilayer insulation material, It works with good refrigerating performance.

C) Neck plug is made of nontoxic plastic good adiabatic property, it has dual role to reduce the liquid nitrogen evaporation and fixed lifting cylinder.

D)Neck tube is enhanced compounds made of glass, it has the extremely low thermal conductivity, can be put into the external heat control at the lowest temperature from cervical canal.

E)WithIn a vacuum, part of which is equipped with a gas adsorbing agent, it can adsorb gas metal vacuum cavity or other substances volatile out, in this way to maintain a high vacuum.
