FARRAR™ 4000 Series Freeze Thaw Chamber
Controlled Rate Freezer Model 4000
Withnell Sensors partners with FARRAR™ to offer the Model 4000 Freeze Thaw Chamber to the UK market. FARRAR™ pioneered forced air convection cooling to meet the challenge of preserving biologic samples and materials. The Controlled Rate Freezer provides consistent, accurate, and brisk freezing and thawing of bulk materials and samples before cold storage. Intended for bioprocessing applications, the Model 4000 freeze thaw chamber drastically reduces freezing and thawing conditioning times, determined in hours, not days or weeks. The precise and rapid freeze thaw chamber safeguards product quality by facilitating timely, uniform bulk freezing and thawing of protein or products stored in a gamut of containers, varying in sizes and shapes (bags, bottles, etc.) including single use system (SUS), polycarbonate vessels or polypropylene vessels. Our cutting-edge Controlled Rate Freezer model 4002/05 (air-cooled) or 4102/05 (water-cooled) executes rapid freezing and thawing for +40˚ C to -80˚ C temperature needs. Farrar's refrigeration experts & Withnell Sensors temperature & humidity specialists assist users plan their process and provide in depth performance data to make sure requirements are met.
