Cryogenisk

Cryogenisk is an adjective used in some languages to describe anything related to cryogenics, the field of physics and engineering that studies the production, behavior, and applications of materials at extremely low temperatures. In practice, cryogenisk covers processes, phenomena, and equipment operating at cryogenic temperatures, typically well below −150 °C (123 K).

Common areas of application include cryopreservation of biological samples and cells, liquefaction and storage of gases such as liquid nitrogen (−196 °C) and liquid helium (−269 °C), and the operation of superconducting devices which require low temperatures. Cryogenisk concepts also appear in research areas like low-temperature physics, where phenomena such as superconductivity and quantum fluids are studied.

Equipment described with cryogenisk include cryostats, dewars, and cryogenic transfer lines, designed to handle extremely low temperatures and manage thermal insulation and safety. Handling cryogenic fluids poses risks including cold burns, condensation and oxygen displacement, requiring proper PPE, ventilation, and pressure-relief systems.

Etymology and usage: The term is formed from roots meaning cold and related notions in several European languages and is used in technical writing to translate or approximate the English cryogenic. It appears in technical manuals, academic papers, and industry literature as an adjective describing processes, equipment, or properties associated with very low temperatures.
