Cryotubes are essential plastic consumables used for the storage of biological samples at low temperatures, typically in cryogenic conditions. Designed to withstand extreme cold, these tubes are made from durable, chemically resistant materials that ensure sample integrity during long-term storage. Cryotubes often feature secure screw caps or snap closures to prevent leakage and contamination, while their graduated markings allow for easy volume measurement. Available in various sizes, they are ideal for storing cells, tissues, or other biological materials. Many cryotubes are also compatible with automated systems, facilitating efficient sample handling and retrieval. By providing reliable containment for samples, cryotubes play a crucial role in research, biobanking, and clinical applications, ensuring that valuable specimens remain viable for future analysis.
