What is the output of the liquid nitrogen machine, "liquid nitrogen" or "nitrogen gas"? In which fields is it mainly applied?
The final product of a standard liquid nitrogen machine is cryogenic liquid nitrogen, which can be directly injected into Dewar flasks or storage tanks for storage and use. At the same time, the equipment is usually equipped with a vaporizer, which can vaporize the liquid nitrogen into normal pressure high-pressure or normal pressure nitrogen for use. Its main application fields include: semiconductor and electronic manufacturing, medicine and biology (sample freezing preservation, pharmaceuticals), food rapid freezing and refrigeration, chemical synthesis, material processing, scientific research and other occasions that require a low-temperature environment or an inert atmosphere.
