Selecting the right liquid nitrogen dewar for cell storage is one of the most consequential equipment decisions a clinical embryologist, biobank manager, or laboratory director will make. The specimens held within a cryogenic vessel in an IVF or biobanking context are often irreplaceable, whether human embryos created through a patients IVF journey, donor gametes, stem cell lines, or primary biological samples that cannot be re-derived. The dewar must provide not just adequate cryogenic performance but reliability, compliance, and safety infrastructure appropriate to the value of what it contains.
For IVF cell storage, vapour-phase dewars have become the preferred standard in progressive clinical programmes. In a vapour-phase vessel, specimens are stored above the liquid nitrogen surface in the cold nitrogen vapour zone rather than submerged in liquid, eliminating any theoretical risk of cross-contamination between samples through the liquid nitrogen medium. Our CryoNest XL and CryoNest XXL vessels are designed with clinical IVF storage requirements in mind.
The inventory management system within the dewar is just as important as the vessel itself. In an IVF clinic where multiple patients specimens are stored together, a well-designed canister, goblet, and cane hierarchy allows for fast, organised retrieval. Use our CBS canisters, Daisy goblets, and Cryocanes for a complete organised storage system.
