NuAire In-VitroCell ES NU-8631 5.65 cu. ft. (160L) Water Jacketed Hypoxic CO2 Incubator with O2 Cont | 5.65 cu. ft. (160L)

Item#: NU-8631
NuAire NU-8631 5.65 cu. ft. water jacketed hypoxic CO2 incubator is designed to provide precise environmental control for cell culture and hypoxia research applications in biotechnology, pharmaceutical, clinical, and academic laboratories. This In-VitroCell ES incubator uses a water jacket heating system surrounding the growth chamber to maintain highly stable temperature conditions while supporting controlled oxygen environments for advanced biological studies. The incubator maintains consistent temperature, humidity, CO2, and oxygen concentrations through infrared CO2 sensing, automated oxygen control with nitrogen injection, and microprocessor regulation to create reproducible low-oxygen culture conditions. Notable features include NuAire’s NuTouch electronic control system with touchscreen monitoring and USB data export, closed-loop HEPA filtration that maintains ISO Class 5 chamber air quality, and a polished stainless steel growth chamber designed for durability and easy cleaning. 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, and a 5.65 cu. ft. (160 L) chamber with adjustable stainless steel shelving.
