NuAire NU-5720 Direct Heat CO2 Incubator Dual Chamber Double Stack
**This double stack incubator has been tested for basic functionality. Unit has slight scratch on right side. See photos for further details.
In-VitroCell model NU-5720 is a CO2 Incubator designed to control relative humidity (RH) levels in the growth chamber better through a sensor and reservoir in place of a water pan. The RH control method allows for greater accuracy to maintain a stable RH percentage by injecting water vapor into the growth chamber to meet the setpoint. RH control is perfect for research samples prone to desiccation or dryer environments.

PRECISE HUMIDITY CONTROL
Relative humidity levels up to 90% are achieved in the growth chamber through the use of a 3-liter reservoir external to the chamber. The chamber air is routed through the water vapor saturated the air in an evaporate box to add humidity when the RH sensor indicates more humidity is needed to meet set point.
DUAL DECONTAMINATION CYCLES
The direct heat technology enables the use of a 145°C dry and 95°C humidified decontamination cycle that can be conveniently run overnight in just 8 hours without removing the CO2 or temperature sensors. The NuTouch control system steps the user through the process with on screen instructions and displays progress throughout each phase of the complete cycle.
Constant Contamination Control
Advanced features mitigate risks due to contamination. Using a slight positive pressure within the chamber eliminates contaminated laboratory air entering the growth chamber. Air and gas pass through 99.99% @ 0.3 micron efficient HEPA filters before entering the chamber resulting in conditions similar to an ISO Class 5 cleanroom. Smooth rounded corners eliminate potential hiding places for contaminates. An overnight procedure running a decontamination cycle at 145° Celsius dry or 95° Celsius humidified is the perfect solution for the fight against contamination. Contamination control is just one more reason NuAire is the safer choice for your laboratory.
Infrared (IR) Sensor
A single source dual wave infrared (IR) sensor controls CO2 levels within the growth chamber to maintain an optimal PH. The wavelengths used are absorbed only by CO2, making the measurements insensitive to other components such as water vapor. Advanced design provides a stable output minimizing drift, and requires less frequent calibrations.
Uniform Temperature
The Direct heating elements or the water jacket are wrapped in high density insulation which surrounds the growth chamber. Dual temperature sensor probes relay information back to the NuTouch Electronic Control System and make adjustments as needed.
