What Nobody Tells You About Choosing a Cryogenic Dewar for Your Lab

 

Most laboratory managers know they need a dewar. Fewer know exactly which type to specify, and the difference matters more than most people realise. Get it wrong and you are either transporting samples in a vessel that was never designed for transit or storing long term material in something built for a day trip.

Two Vessels, Two Very Different Jobs

A dry shipper dewar looks similar to a storage dewar from the outside. Inside, they are completely different. A dry shipper holds nitrogen in an absorbent lining. There is no free liquid. This makes it safe to tip, safe to fly, and approved under IATA regulations for air transport of biological material. It is the right vessel for any laboratory sending samples between sites.

A storage dewar holds free liquid nitrogen. It sits on your laboratory floor, it does not move, and it maintains your samples at minus 196 degrees Celsius for months at a time. It is the right vessel for any laboratory that needs long term liquid nitrogen dewar cell storage.

The CryoStork V2 and CryoNest XXL

Cryolab supplies the CryoStork V2 for transport and the CryoNest XXL for laboratory storage. Both are held in UK stock and available for next-day delivery. Both come with direct UK technical support from a team that has been supplying cryogenic equipment to British laboratories for over two decades.

If you are not sure which vessel your laboratory needs, or you need both, contact Cryolab at info@cryolab.co.uk or call 01243 837177. The team will give you a straight answer.

IVG: The Quiet Scientific Revolution That Could Change Everything About Fertility Treatment

Image
Most major shifts in medicine do not arrive with fanfare. They arrive in research papers, conference presentations, and careful laboratory work that takes years to reach the people it could help. In-vitro gametogenesis, known as IVG, feels like one of those shifts. The premise is remarkable in its simplicity. Take an ordinary adult cell, a skin cell or a blood cell, reprogram it into a stem cell, and then guide it through the biological processes that produce a mature egg or sperm. No surgical retrieval. No hormone stimulation. Just cells, carefully coaxed into becoming something extraordinary. Professor Katsuhiko Hayashi of the University of Osaka has stated that viable human eggs and sperm created this way could be a reality within ten years. His work and that of colleagues at the University of Kyoto has been among the most cited in this field. California-based Conception Biosciences, with investment from Sam Altman among others, is working toward the same goal from a commercial an...
