A cryogenic storage vessel is a vacuum-insulated container designed to store biological samples in liquid nitrogen at minus 196 degrees Celsius. In IVF laboratories, storage vessels are used for long-term holding of embryos, oocytes and sperm in sealed, labelled straws organised within goblets and canisters. Vessels vary in capacity, neck diameter and static evaporation rate. Narrow-neck vessels retain liquid nitrogen longer and suit static storage programmes. Wider-neck vessels allow easier sample access and suit high-frequency retrieval workflows. Cryolab supplies the CryoNest series for large-capacity storage and the CryoCan series for compact laboratory storage. View the full storage vessel range at cryolab.co.uk.
