Nitrogen for multi-gas incubators
(tri-gas)

What is a multi-gas incubator (tri-gas)?

Multi-gas or tri-gas incubators are incubators with variable oxygen control. They provide optimal conditions for the cultivation of cell cultures in the pharmaceutical industry, medicine, food analysis and biochemistry. Through the precise regulation of temperature, humidity, and CO₂ and O₂ levels, they create a controlled, physiologically relevant environment.

Why nitrogen is important for multi-gas incubators

For many cell types, a low-oxygen environment is crucial for promoting growth, vitality and longevity. This is precisely where the supply of nitrogen plays a key role. By introducing nitrogen, the oxygen content in the incubator is reduced and kept stable – a significant advantage for sensitive or hypoxic cell cultures. A regulated supply of nitrogen enables:

Accelerated cell growth
Longer cell viability
Reduced cellular stress
Reproducible culture conditions

Nitrogen generator for cell culture

A nitrogen generator for cell culture applications continuously supplies pure nitrogen directly on site – safely, cost-effectively and without the need for gas cylinders. This makes the supply to multi-gas incubators more reliable and minimises the logistical and storage requirements. Advantages of a nitrogen generator

Stable, continuous nitrogen supply
No need to change gas cylinders
More cost-effective and safer operation

Conditions close to those found in nature through controlled oxygen reduction

Cells from areas of the body with low oxygen concentrations – typically between 1 % and 14 % O₂ – benefit particularly from a targeted supply of nitrogen. As the atmosphere has an O₂ content of approximately 20–21%, nitrogen in the multi-gas incubator ensures a realistic, growth-promoting environment. This controlled atmosphere is crucial for applications such as:

Hypoxia research
Stem cell cultures
Tissue engineering
Primary cell cultures
