NuAire In-VitroCell ES NU-8645 Water Jacketed CO2 Incubator | 5.65 cu. ft. (160L)

Item#: NU-8645

NuAire NU-8645 5.65 cu. ft. water jacketed CO2 incubator is designed to provide precise environmental control for mammalian cell culture and biological research applications in biotechnology, pharmaceutical, clinical, and academic laboratories. This In-VitroCell ES incubator uses an 18-gallon water jacket surrounding the growth chamber to maintain highly stable temperature conditions while supporting controlled oxygen environments for hypoxia and advanced tissue culture studies. The system maintains consistent temperature, humidity, CO2, and oxygen concentrations using infrared CO2 sensing, a zirconia oxygen sensor with nitrogen suppression capability, and microprocessor-based environmental control. Chamber air cleanliness is maintained through an ISO Class 5 closed-loop filtration system with 99.97 percent efficient capsule filters and positive pressure airflow to reduce contamination risk. The incubator includes the NuTouch touchscreen control system with USB, RS-485, and 4-20 mA data output for monitoring and integration with laboratory monitoring systems. Additional design features include a polished stainless steel chamber with coved interior corners for easy cleaning, adjustable stainless steel shelving, magnetic outer door gasket, silicone inner door seal, and optional segmented inner doors for improved workflow access. Key specifications include a temperature control range from 5°C to 55°C with ±0.2°C uniformity at 37°C, CO2 control from 0.1% to 20% with ±0.1% accuracy, oxygen control from 0.5% to 21% with ±0.25% accuracy, humidity capability up to approximately 95% RH using a stainless steel water pan, and a 5.65 cu. ft. (160 L) chamber supporting up to 16 adjustable shelves.
