The 20-liter liquid nitrogen dewar is one of the most versatile and widely specified cryogenic storage vessels in UK clinical and research settings, offering a practical combination of capacity, portability, and hold time that suits a wide range of applications from small IVF clinics through to university research laboratories and veterinary AI practices.
A 20-liter liquid nitrogen dewar typically offers a static hold time of between 60 and 180 days depending on the neck diameter and the quality of the vacuum insulation, a static evaporation rate of between 0.05 and 0.2 litres per day, and a canister capacity of three to six canisters depending on the model. Cryolabs CryoCan 30-6 offers an excellent specification in this size class and is compatible with our full range of storage accessories including CBS canisters, Daisy goblets, Classic goblets, and Cryocanes.
In an IVF setting, a 20-liter dewar is best suited as a working vessel for a small clinic with a modest patient load, as a secondary vessel complementing a larger primary archive store such as the CryoNest XL, or as a dedicated vessel for a specific subset of specimens. For larger capacity requirements, the CryoCan 47-6 and CryoCan 47-10 offer significantly greater capacity with longer hold times.
