LONDON - s4story -- If you work in a laboratory, IVF clinic or fertility centre, a reliable LN2 storage dewar is one of the most critical pieces of equipment you will own. Whether you are storing embryos, oocytes, sperm samples or biological specimens, the right liquid nitrogen dewar keeps your samples safe, stable and accessible.

What Is an LN2 Storage Dewar?

An LN2 storage dewar is a vacuum-insulated vessel designed to store liquid nitrogen and the biological or cryogenic materials held within it. They come in a range of sizes, from small bench-top units to large floor-standing vessels holding 50 litres or more. The vacuum insulation minimises heat transfer, keeping contents at the ultra-low temperatures required for long-term cryogenic storage.

A storage dewar is designed for static, long-term storage in a fixed location. A dry shipper, by contrast, is built for transporting cryogenic samples, with an absorbent core that holds liquid nitrogen safely during transit. If you need both storage and shipping capability, you will need both types.

Choosing the Right Storage Dewar for Your Needs

The right dewar depends on your application. IVF clinics typically require dewars with high canister capacity and precise inventory management, while B2B laboratories may prioritise volume and low evaporation rates. Key factors to consider include holding time, static evaporation rate, neck diameter, and number of canisters supported.
