Controlled Rate Freezers News

Introduction
Grant CRFT controlled rate freezer from Wolflabs.
The CRFT brings accuracy, precision, and reproducibility to biological cryopreservation. This unit is ideal for research into the cryopreservation of a wide range of material including embryos, stem cells, mammalian cells, spermatozoa, antibodies, tissue sections and rodent organs.

Features and benefits
- Accurate and reproducible control of cooling rates and sample temperatures
- Interchangeable heads
- Controlled thawing system
- Easy to use and samples can be nucleated/seeded in-situ
- Linear and non-linear cooling profiles
- Low running costs: estimated at 1% of liquid nitrogen-controlled rate freezing

Introduction
Grant CRF-1 controlled rate freezer from Wolflabs. 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 CRF-1 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. 

Features and benefits
- 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.
- Low running costs.
- Temperature remains at -100°C at the end of cycle for straw applications until freezer is switched off.
- CE marked.
- 3 year warranty.
