NuAire In-VitroCell ES NU-5741 Hypoxic Direct Heat CO2 Incubator Dual Sterilization, Humidity/O2 Control | 5.65 cu. ft. (160L)

Item#: NU-5741

NuAire NU-5741 5.65 cu. ft. 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 CO2 incubator supports advanced cell culture workflows by regulating temperature, humidity, CO2, and oxygen levels to simulate physiologic and low-oxygen environments used in stem cell research, cancer biology, and tissue culture studies. The incubator maintains stable chamber conditions through direct heat temperature control, dual-wave infrared CO2 sensing, and automated oxygen regulation using nitrogen injection to achieve hypoxic setpoints. Notable features include dual sterilization cycles at 145°C dry heat and 95°C humidified for contamination control, a closed-loop HEPA filtration system that maintains ISO Class 5 air quality within the chamber, and the NuTouch touchscreen electronic control system for easy monitoring and parameter adjustment. Key specifications include a temperature control range from 5°C to 55°C with ±0.3°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 regulation up to 95% RH, and a 5.65 cu. ft. (160 L) chamber with adjustable stainless steel shelving.

  • NuTouch Electronic Control System: The NU-5720 is equipped with the user-friendly NuTouch Electronic Control system, which is a touchscreen system that makes managing the incubator easy.
  • Hypoxic Conditions: The chamber of the incubator can offer hypoxic conditions, using a sensor for O2 control and injecting N2 gas to meet a set point in a range of 0.5 percent to 21 percent, accurate with ±0.25 percent.
  • Dual Sterilization Cycles: The NU-5741 incubator is engineered with dual sterilization cycles to protect both products in the chamber and personnel in the lab. The dual cycles are at 145°C dry and 95°C humidified.
  • Designed for Protection: The incubator was designed with a coved corner and crevice-free interior, which makes it both easy to clean and limits potential hiding places for contamination.
  • Closed-Loop HEPA Filtration: The closed-loop HEPA filtration system in the NU-5741 model incubator was also designed to minimize the risk of contamination. The system is similar to that of an ISO class 5 clean room, maintained at a positive pressure, with gas and air continuously passing through 99.99 percent efficient HEPA filters.
  • No Vibration: The incubator has no vibration since there are fewer moving parts. The reduced vibration helps protect cell lines.
  • Humidity Control: Humidity control in the NU-5741 is managed through a three-liter reservoir that injects water vapor to meet a set point up to 95 percent. This system is used in the incubator in place of a user water pan. The humidity control system is accurate within +5 percent / -3 percent.
  • Faster Recovery Times: The NU-5741 incubator features faster recovery times after door openings, which helps maintain temperature, CO2 gas and O2 levels.
  • Accurate CO2 Levels: There is a dual wave infrared sensor in the incubator that helps maintain proper CO2 concentrations in the growth chamber, accurate within ±0.1 percent. The sensor is insensitive to other components, such as water vapor.
  • Uniform Temperature: The uniform temperature in the incubator (±0.3C) is monitored using dual temperature probes.
Temperature Control:
  • Control Range: 5°C to 55°C (37°C default) (5°C above ambient to 30°C maximum ambient)
