Liquid nitrogen free and cryogen free controlled rate freezer for the cryopreservation of a wide range of material including: embryos, stem cells, mammalian cells, spermatozoa, antibodies, tissue sections and rodent organs. The EF600M brings accuracy, precision and reproducibility to biological cryopreservation.

Unlike conventional liquid Nitrogen based controlled rate cooling equipment used in IVF laboratories, the EF600M poses no contamination risk and can be used in cleanrooms and barrier facilities. The EF600M fits neatly and quietly on a bench-top and its performance in terms of cell viability after freezing is comparable or better than standard liquid nitrogen freezers. As alcohol is not used, there is also no potential fire risk. The EF600M will cool down to – 100ºC with straws.

The cooling rate of the EF600M is precisely controlled, ensuring accuracy and reproducibility throughout the freezing profile especially for the important nucleation/seeding phase. This ensures optimal recovery of cells upon thawing. Operation is simple and can be carried out with or without a PC; data can be logged via PC software and cooling profiles are directly displayed. Different cooling profiles are available from a drop down menu and customised profiles can be written. Published trials have demonstrated successful freezing and recovery of embryos, sperm and embryonic stem cells.
