Cryogenic vials are a type of laboratory consumable that are designed for the long-term storage of biological samples at extremely low temperatures, typically at -80°C or lower. They are made of materials that are resistant to extreme cold and are typically made of polypropylene, polycarbonate or other high-density plastics.
Cryogenic vials come in various sizes ranging from 0.5 ml to 5 ml and are designed to be used with a variety of storage systems, such as cryogenic boxes or racks. They may also come with special features, such as externally threaded caps or silicone gaskets, to ensure proper sealing and to prevent contamination of the sample. Cryogenic vials are commonly used in molecular biology, cell biology, and microbiology laboratories for applications such as long-term storage of DNA or protein samples. Proper labeling, handling, and storage of cryogenic vials is important to maintain the integrity and accuracy of laboratory samples, as well as to ensure the safety of laboratory personnel who handle them.
