DIRECT HEAT | 200-LITER CAPACITY | OXYGEN SUPPRESSION | HUMIDITY CONTROL
The In-VitroCell model NU-5841 is a direct heat CO2 incubator that features an RH sensor and water reservoir in place of a water pan to control the growth chamber’s humidity levels to the setpoint. In addition, the NU-5841 also offers the ability to suppress oxygen levels by monitoring O2 levels in the chamber and injecting nitrogen gas to meet the setpoint. A large 7.06 ft3 (200 Liter) capacity chamber is a perfect solution for principal investigators looking for a robust solution for hypoxic stress studies, stem cell culture research, and more.

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.
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.
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.
