Controlled Rate Freezers
Controlled Rate Freezers are used to prepare samples prior to storing them at Cryogenic temperature and to protect sample from thermal shocks, ensuring maximum viability. As water constitutes around 80 % of tissue mass, CRF is used to freeze the samples at a cooling rate without formation of ice or crystals in the sample.
Salient Features:
- Inbuilt Laptop controller with Windows based operating system.
- Unlimited programming capability.
- Multi-color graphing of sample, chamber and program temperature.
- Temperature set points by sample or chamber.
- Material : Inside Stainless Steel 304, Exterior powder coated steel
- Door: Hinged, stainless steel chamber door
- Continuous control status indication on LCD display
- Programs and freeze data saved to hard drive or disc.
- Password protected software, 21 CFR Part 11 compliant
- Searchable database for unlimited freeze run history.
- Freeze run graphs and data available via any standard USB printer.
- 30 configurable data fields available for each freeze run.
- Continuous digital and graph display for time and temperature during operation.
- Manual overrides for all operating functions.
- Temperature measurement via 2 Type T thermocouples
- Heater installed for warming between runs
- Foam insulated with Teflon impregnated gasket (PTFE)
- Six pre-set easy to run freeze programs
- Safety valve installed to release the excess pressure
- Audible and Visual Indicators
