In-VitroCell ES (Energy Saver) model NU-5820 Direct Heat CO2 Incubator provides a reliable, controlled in-vitro environment suitable for growing tissue cell cultures. Model NU-5820 features dual sterilization cycles at 95 degree C humidified and a 145 degree C dry. A microprocessor-based dual wave infrared (IR) sensor controls CO2 levels and a RH sensor controls relative humidity inside the chamber for cells that are prone to desiccation.
