Cryogenic containers are specialized vessels designed to store materials at extremely low temperatures, typically below -150 degrees Celsius. These containers are essential for preserving biological samples, such as cells and tissues, as well as for storing liquefied gases like liquid nitrogen and helium. Their insulation helps maintain the cold environment, preventing heat transfer from the outside. These containers come in various sizes and designs, including portable units for fieldwork and larger tanks for laboratory use. They are often made from materials that can withstand the stresses of low temperatures, ensuring safety and reliability in applications ranging from medical research to space exploration.
