The Dry Phase storage solution designed and patented by Cryo Diffusion is a unique solution to provide safer storage conditions for the samples and to offer greater safety for the operator. The samples (rack or canisters) are placed inside a sump (dry section) which is fixed inside the cryogenic vessel and immerged into liquid Nitrogen. The dry sump is specifically designed to fit to the inventory system being used inside the vessel (racks or canisters), ensuring that the samples are always maintained at -195°C to -185°C, even if the lid has been accidentally left open for several hours.
The Dry Phase solution allows the samples to be maintained at cryogenic temperatures with the minimum amount of temperature variation compared to traditional Gas Phase storage conditions offered by other manufacturers. The samples stored also have no contact with liquid Nitrogen avoiding any possible risk of cross contamination and also the design is intrinsically safe for the operator and there is minimal risk of cold burns compared to other storage solutions. This technology was introduced by Cryo Diffusion since 1987 and has proved to be superior to other systems on the market and (over time), will replace traditional Liquid and Gas Phase storage systems for critical cryogenic storage.
All these tanks can be equipped with an electronic controller S170 for automatic filling, liquid level and temperature control, with local and remote alarms and connection RS485 for cryobank supervision.
