Abstract:
The biological storage equipment for liquid nitrogen has gone through three main development stages:biological container for liquid nitrogen,large-diameter container for liquid nitrogen,and tank for gas-phase liquid nitrogen,becoming a cross-product with multidisciplinary integrating cryobiology,vacuum and cryogenics technique,intelligent control technique and mechanical manufacturing.With the development of biological storage equipment for liquid nitrogen,a great deal of application achievements have been obtained in cryogenic insulation technology,vacuum technology,structure design,manufacturing process and experimental research in China.In view of the demand of the construction for large-scale biological sample bank in China,some key technologies and solutions in the development of the tank for gas-phase liquid nitrogen towards integration,intelligence and green were reviewed in this paper.At the same time,in order to make the tank for gas-phase liquid nitrogen,a new product,to suit for the development of industrial intelligence in China,we proposed suggestion to incorporate this kind of product into the standardized management as soon as possible.
