The Grant CRF-1 controlled rate freezer is suitable for cryopreservation research of a wide range of material, including: embryos, stem cells, mammalian cells, spermatozoa, antibodies, tissue sections and rodent organs.
Unlike conventional liquid nitrogen-based, controlled rate cooling equipment, the CRF-1 poses no contamination risk and can be used in cleanrooms and barrier facilities. The CRF1 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.
The cooling rate of the CRF-1 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.
