Model NU-5710 is a CO2 incubator that utilizes heating elements that surround the growth chamber on five sides. An independent door heater helps maintain temperature uniformity and reduce condensation. This direct heat model offers optimal cell growth conditions by producing humidity levels up to 95% and precisely controlling CO2 gas and temperature levels while minimizing potential contamination.


The In-VitroCell™ ES NU-5710 5.65 Ft3 (160 Liter) Direct Heat CO2 Incubator is designed to provide lab workers with a controlled in-vitro environment for growing tissue cell cultures. The NU-5710 provides optimum growth conditions via several parameters, including humidity, precise temperature control, precise CO2 control, sterility and reliability.

The incubator's chamber can also be used for the preservation and storage of embryos, gametes and animal cell cultures intended for research at body temperature.

Outstanding Technology

NuTouch Electronic Control System

The NU-5710 is equipped with the user-friendly NuTouch Electronic Control system, which is a touchscreen system that makes managing the incubator easy.

Designed for Contamination Control

Dual Sterilization

To protect laboratory personnel and the products in the chamber, the incubator is engineered to keep contamination to a minimum. The NU-5710 offer dual sterilization cycles -- at 145 °C dry and 95 °C humidified.

Protective Design

The incubator has also been designed to minimize potential hiding places for contamination. It has coved corners and a crevice-free interior, which makes it easy to clean.

Closed Loop HEPA Filtration

For maximum contamination control, the NU-5710 incubator is designed with a closed loop HEPA filtration system. Using standards similar to an ISO Class 5 Clean Room, the incubator's filtration system is maintained at positive pressure while gas and air continuously pass through the 99.99-percent effective HEPA filters.

Minimal Vibration

For product protection, the incubator has fewer moving parts, which means reduced vibration. Reducing vibration helps protect cell lines.

Performance Features

Fast Recovery Times

The NU-5710 incubator has faster recovery times after door openings for both temperature and CO2 gas.

Temperature Accuracy

A dual wave infrared (IR sensor) within the incubator maintains accurate CO2 levels in the growth chamber, which are accurate within ±0.1 percent, and it is insensitive to other components within the chamber, such as water vapor.

Temperature Uniformity

The incubator is able to maintain a uniform temperature, ±0.3 °C, and this temperature is monitored using dual temperature probes, to ensure optimal product growth and health.

Simple Humidity Control

Humidity control in the NU-5710 is simple. The relative humidity level of up to 95 percent is achieved through the use of a stainless steel pan filled with distilled water no purer than 1 mega ohm, placed on the bottom of the chamber.
