Liquid nitrogen free and cryogen free controlled rate freezer for research into the cryopreservation of a wide range of material including: embryos, stem cells, mammalian cells, spermatozoa, antibodies, tissue sections and rodent organs. For use in cleanrooms and barrier facilities.

• Accurate and reproducible control of cooling rates and sample temperatures
• Easy to use and samples can be nucleated/seeded in-situ
• Linear and non-linear cooling profiles
• Operation can be carried out with or without a PC
• Low running costs: estimated at 1% of liquid nitrogen controlled rate freezing
• Temperature remains at -100 °C at the end of cycle for straw applications until freezer is switched off
