CO2 Incubator vs Tri-Gas Incubator: Which One Do You Need?

Selecting the correct cell culture incubator is important for maintaining stable and reproducible growth conditions. Although CO2 and tri-gas incubators appear similar, their gas-control capabilities make them suitable for different applications.

What Is a CO2 Incubator?

A CO2 incubator controls temperature, humidity and carbon dioxide concentration to support routine cell and tissue culture. CO2 helps maintain the correct pH level in common bicarbonate-buffered culture media.

Kenton CR Series CO2 Tissue Culture Incubators provide a CO2 control range of 0 to 20%, infrared sensing, PID touchscreen control and natural humidification. They are suitable for microbiology, life science, pharmaceutical and biological research.

What Is a Tri-Gas Incubator?

A tri-gas incubator controls CO2 and oxygen while using nitrogen to create the required oxygen concentration. This allows researchers to reproduce low-oxygen or other specialised atmospheric conditions.

Kenton CST Tri-Gas Incubators provide CO2 control from 0 to 20% and oxygen control from 1 to 25%. They are suitable for hypoxic cell culture, cancer research, stem-cell studies and other applications requiring precise oxygen regulation.

Which Incubator Should You Choose?

Choose a standard CO2 incubator when your work requires stable temperature, humidity and CO2 control under normal oxygen conditions. It offers a practical solution for most routine cell-culture applications.

Choose a tri-gas incubator when oxygen concentration directly affects your research. Although it requires an additional nitrogen supply and more gas management, it provides greater control over specialised culture environments.

Both systems should provide accurate temperature control, rapid gas recovery, contamination prevention and an easy-to-clean SUS304 stainless steel cavity.
