A plastic cryovial tube, also known as a cryogenic vial or cryotube, is a specialized type of plastic tube designed to store biological samples, such as cells, tissues, or other biological materials, at extremely low temperatures. These tubes are commonly used in various fields, including biomedical research, clinical laboratories, and cryopreservation.

Here are some key features and characteristics of plastic cryovial tubes:
1.Material: Plastic cryovial tubes are typically made from high-quality, durable materials such as polypropylene or polyethylene. These materials are chosen for their excellent resistance to low temperatures and their ability to withstand the freezing and thawing cycles involved in cryopreservation.
2.Screw-cap design: Cryovial tubes usually have a screw-cap design to ensure a secure and leak-proof seal. The cap is threaded to the tube, providing a tight closure that prevents the entry of contaminants and minimizes the risk of sample loss or contamination during storage.
3.Graduations and labeling area: Many cryovial tubes come with graduations or volume markings on the side, allowing for accurate sample measurement and easy identification of sample volumes. Additionally, there is often a designated area on the tube or cap for convenient sample labeling, ensuring proper sample identification.
4.Cryogenic compatibility: Plastic cryovial tubes are designed to withstand extremely low temperatures, typically ranging from -80°C to -196°C (-112°F to -321°F). This makes them suitable for long-term storage in ultra-low temperature freezers or in liquid nitrogen storage systems.
5.Sterility: Cryovial tubes are commonly available in sterile formats, ensuring that the samples stored inside remain uncontaminated. Sterility is particularly crucial for applications involving cell culture or sensitive biological materials.
