kryosäiliö

A kryosäiliö, often translated as cryogenic storage tank or cryotank, is a specialized container designed for the safe and long-term storage of substances at extremely low temperatures, typically below -150 degrees Celsius (-238 degrees Fahrenheit). These tanks are engineered to minimize heat transfer from the environment, thereby maintaining the cryogenic state of their contents.

The construction of a kryosäiliö usually involves a vacuum-insulated double-walled vessel. The inner wall contains the cryogenic substance, while the outer wall provides structural integrity and protection. The space between the walls is evacuated to create a vacuum, which is an excellent insulator. Additional insulation materials may be incorporated to further reduce heat ingress.

Kryosäiliöt are essential in various scientific, medical, and industrial applications. In scientific research, they are used to store liquefied gases like liquid nitrogen and liquid helium, which are crucial for experiments requiring extremely low temperatures. In medicine, they are vital for preserving biological samples such as blood, tissues, stem cells, and reproductive cells through cryopreservation. Industrially, they are employed for storing and transporting industrial gases like oxygen, nitrogen, and argon in their liquid forms.

The design and materials used for a kryosäiliö depend on the specific cryogenic substance and its required storage temperature, as well as safety regulations and intended use. They come in various sizes, from small laboratory dewars to large industrial tanks.
