The EF600 is the world's first liquid nitrogen free controlled rate freezer. It has been specifically designed for use in human and veterinary IVF for the cryopreservation of embryos, spermatozoa and stem cells, but can also be used for a wide range of freezing applications.
The EF600 is electrically powered by a Stirling Cycle Cryocooler, not liquid nitrogen. This allows the freezer to be used in laboratories which operate under sterile conditions or which require high air quality, and presents no risk of contamination to samples. The cooling rate is precisely controlled allowing good recovery on thawing.
Grant Instruments manufacture and market the EF600; contact them directly regarding sales and for details of distributors. This website is designed to act as the technical repository for the EF600.
