Liquid nitrogen storage tanks are meticulously engineered to provide an unparalleled environment for the long-term preservation of delicate biological materials.
The liquid nitrogen storage tank is a double-layer fixed vacuum powder insulated storage tank. The inner tank is made of stainless steel, and the outer tank is made of Q235B or Q345R.
Cryogenic tanks are often called cryogenic tanks or liquid nitrogen tanks. The structure is divided into two layers, the inner layer is made of austenitic stainless steel. The outer layer is made of an intermediate layer filled with insulation.
For most products, long-term storage in the refrigerator leads to product quality degradation, but for example, fruits such as bananas and oranges can be stored at 0℃ for several days, -30℃ for 1 week, and -50℃ for 2 months.
