FARRAR® pioneered forced air convection cooling to answer the challenge of preserving biologic samples and materials. The Controlled Rate Chamber (model 4000 series) provides repeatable, precise, and rapid freezing and thawing of bulk materials and sample prior to cold storage.

Our Model 4000 series rate chamber, purpose-built for bioprocessing applications, greatly reduces freeze/thaw conditioning times, measured in hours, instead of days or weeks.

This precision controlled rapid freeze/thaw chamber helps protect product quality by enabling fast, uniform bulk freezing and thawing of protein or products in a variety of containers of various sizes, (bags, bottles, etc.) including single use system (SUS), polycarbonate vessels or polypropylene vessels.

Our high-performing Controlled Rate Chamber model 4002/05, (air-cooled) or 4102/05, (water-cooled) conducts rapid freeze/thaw for +40°C to -80°C temperature needs. FARRAR's refrigeration experts help customers plan their process and provide performance data to ensure requirements are met.

• Wide-range temperature capability for nearly any application (+40°C to -80°C)
• Air or water-cooled options available
• Uniform, repeatable results to help ensure quality control
• Cycle start/stop with +/-1°C product temperature tolerance
• Sizable and powerful cooling capacity achieves steady state in 38min (empty chamber) and is capable of freezing 100L to -80°C in 12h
