Cryogenic storage refers to the process of preserving materials at extremely low temperatures, typically below -150 degrees Celsius (-238 degrees Fahrenheit). This method is commonly used to store biological samples, such as cells, tissues, and reproductive cells, to maintain their viability and prevent degradation over time. In addition to biological applications, cryogenic storage is also utilized in various industries, including liquid nitrogen storage for industrial gases and space exploration for preserving fuel and equipment. The technology relies on specialized containers, known as cryostats, to maintain the necessary low temperatures and ensure the safety of the stored materials.
