In-VitroCellNU-8645
Water Jacket CO2 Incubator
Water Jacket | 160-Liter Capacity | Oxygen Suppression | Humidity Monitor
The In-VitroCell NU-8645 CO2 Incubator uses a water jacket to control and maintain the temperature in the growth chamber. In addition, model NU-8645 features an oxygen suppression system to control O2 levels between 0.5 to 21 percent for mammalian tissue culture research. The NU-8645 uses a water pan and convection to generate up to 95% humidity levels. Monitor relative humidity in the chamber through an RH sensor and display the percentage on the incubator touchscreen controls. In-VitroCell NU-8645 provides uniform and stable growth conditions for cell culture research.

Precise Uniformity
Water Jacket Temperature Control
In-VitroCell Water Jacket CO2 Incubators maintain accurate temperature with the large 18 gallons (68.1-liter) water jacket that surrounds the inner chamber. Heated water in this jacket circulates around the growth chamber, keeping the temperature uniform within the growth chamber ±0.2°C. Precise temperature control is aided by the R5 insulation that lines the outer chamber walls that minimize heat loss.
The door and perimeter heaters are microprocessor-controlled to adjust to the room's ambient temperature. They can also be adjusted manually from ±20 percent to reduce condensation within the growth chamber.

Easy to Clean, Minimize Contamination Risks
Coved Interior Corners
NuAire CO2 incubators are designed to minimize potential hiding places for contamination. Coved corners and a crevice-free interior, which makes it easy to clean.
