Select a step where Air Liquide intervenes in your value chain.



Biomanufacturing – cell culture

Upstream bioprocessing applications require a mixture of oxygen (O2), nitrogen (N2), and carbon dioxide (CO2). This mixture is sparged through the cell culture media to provide replenishment of oxygen during cell growth.

In addition, carbon dioxide is used for pH control, while nitrogen is used to strip excess carbon dioxide out of solution and balance the overall flow rate. With Air Liquide, you can be confident in the reliability and quality of the gas supply for your controlled atmospheres.



We provide gas handling safety expertise and a range of resources, including Certificates of Analysis (CoA) upon request.
