Grant Instruments CRF-1 Controlled Rate Freezer

Description

This listing is for a Grant Controlled Rate Freezer - CRF-1 The unit is in full working condition and is ready for immediate release Product Overview: The CRF-1 Liquid Nitrogen-Free Controlled Rate Freezer is designed for precision-controlled freezing and cryopreservation of biological samples, such as embryos, stem cells, mammalian cells, spermatozoa, antibodies, tissue sections, and rodent organs. Unlike conventional liquid nitrogen-based freezers, the CRF-1 is liquid nitrogen and cryogen-free, eliminating contamination risks and making it suitable for use in cleanrooms and barrier facilities. It offers superior performance in terms of cell viability post-freezing and poses no fire hazard, unlike alcohol-based systems. The CRF-1 allows for highly accurate, reproducible, and controlled freezing rates, crucial for the cryopreservation of biological samples, ensuring optimal recovery upon thawing. Key Features: Cryogen-Free Design: The CRF-1 is free from liquid nitrogen and alcohol, offering a safer, cleaner alternative to traditional freezing methods. No contamination risk, making it ideal for use in sterile environments. Precise Cooling Control: The cooling rate is accurately controlled, especially for the critical nucleation/seeding phase, which ensures consistent and optimal recovery of cells. Wide Temperature Range: Capable of cooling down to -100°C with straws, offering a broad application range for biological cryopreservation. Simple Operation: The CRF-1 operates with or without a PC, and it can log data via PC software. Cooling profiles are displayed directly and can be customized. High Versatility: Compatible with cryovials, straws, bags, microplates, and Matrix-96-well block plates, allowing for research across multiple areas like stem cell research, transgenic embryos, mammalian cells, and more. Low Operational Costs: The CRF-1 runs at approximately 1% of the cost of liquid nitrogen-based freezing systems. Safety Features: Includes an optional Un-interruptible Power Supply (UPS) for complete cycle continuation in case of power failure. Compact & Quiet: Fits neatly on a bench-top and operates quietly, making it suitable for laboratory settings. Main Applications: Transgenic embryos research Stem cell research Clinical and research samples like lymphocytes and tissue cell lines Mammalian cell preservation (e.g., cardiomyocytes, adipose, liver, muscle) Cord blood-derived stem cells Adherent cells and stem cells in microplates Cell suspensions in numbered/barcoded arrays Robotic integration for high-throughput applications Veterinarian IVF applications Technical Specifications: Dimensions (w x d x h): 264 x 367 x 445 mm Weight: 9.8 kg Max Plate Temperature: 30°C Min Plate Temperature: -80°C (standard) or -100°C (dependent on model) Temperature Accuracy: ±0.5°C Temperature Stability: ±0.1°C Temperature Uniformity: ±1.0°C Max Cooling Rate: 10°C/min Max Temperature Stabilization Time: 5 minutes Key Benefits: Accurate and Reproducible Cooling Rates: Ensures controlled freezing rates and precise sample temperature management. Customizable Cooling Profiles: Choose from linear and non-linear profiles, or create your own tailored profile. No Cryogen or Liquid Nitrogen: Ideal for reducing contamination risk and the cost of liquid nitrogen. Low Running Costs: Estimated to cost only 1% of traditional liquid nitrogen-controlled freezing methods. End-of-Cycle Cooling Stability: Maintains a steady -100°C temperature for straw applications until the freezer is switched off. CE Marked: For laboratory use in compliance with safety and quality standards. The unit is in full working condition and is ready for immediate release
