Water Jacket CO2 Incubator

Water Jacket | 160-Liter Capacity | Temperature & CO2 Control | HEPA Filtration

The In-VitroCell NU-8600 Water Jacket CO2 incubator offers modern control and monitoring of temperature and CO2 levels inside a traditional water jacket design for applications prioritizing stability and security. Beyond using an infrared sensor for precise control of CO2 and a 68-liter water jacket for reliable and uniform internal temperature. The air pump is located outside the 160-liter stainless steel chamber that constantly draws air through a HEPA filter and cycles it back to the growth chamber. This closed-loop HEPA filtration system helps to create ISO Class 5 quality air at positive pressure to minimize contamination. A touch screen makes it easy to enter set points and view or download historical performance. In addition, this moderately sized incubator can be stacked to efficiently use the valuable space in your laboratory.

The Modern User Experience you Expect

NuTouch Control System

The NuTouch control system provides you with the user experience you have come to expect from any piece of modern equipment. Change set points, view chamber history, start a decontamination cycle, or perform a calibration procedure from this simple interface. All NuAire CO2 incubators standardize on the NuTouch control system, meaning that once users learn to navigate one incubator they can move seamlessly to any other in the lab.

CO2 Incubator Water Jacket Temperature Control

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.


Cell Cultures Deserve Their Own Clean Room

Closed Loop HEPA Filtration

Continual HEPA filtration of chamber air complements periodic high heat decontamination to provide Constant Contamination Control. InVitrocell’s design constantly takes a sample of air from the chamber, routes it through a HEPA filter in a compartment outside that inner chamber, and ultimately returns it to create an ISO Class 5 level of clean air in the interior as well as a slight positive pressure. Inside the InVitrocell, your cell cultures are protected by a multi-tiered defense against contamination.

CO2 Incubator Coved Interior Corners

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.
