What is a cryogenic tube?

A cryogenic tube is a specialized container designed to store and transport materials at extremely low temperatures, typically below -150 degrees Celsius (-238 degrees Fahrenheit). These tubes are often used in scientific research, medical applications, and industrial processes to preserve biological samples, cryogenic fluids, or other temperature-sensitive substances. Their construction usually involves materials that minimize heat transfer and ensure insulation, such as vacuum-sealed layers.
