Description
Grant CRFT 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 CRFT poses no contamination risk and can be used in cleanrooms and barrier facilities. The CRFT 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 CRFT 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.
Interchangeable heads must be ordered separately.
Features
- 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: Estimated at 1% of LN2 controlled rate freezing
- Temperature remains at -100°C at the end of cycle for straw applications until freezer is switched off
- Alcohol is not used, so there is no potential fire risk
- Uninterruptible Power Supply (UPS): Complete cycle run if power fails (available as an optional accessory)
- Various fixed plates available: Standard straws, high security straws, cryovials, cryocyte bags and microplates*
- Cleaning: Seamless, no dirt traps, may be cleaned using standard wipes
- Servicing and calibration available
- Two year parts and labour warranty
