FC-40 is widely used in biomedical and laboratory applications due to its inertness and high oxygen solubility. It is commonly employed in liquid ventilation, where it helps deliver oxygen directly to the lungs in certain medical treatments. FC-40 is also used in cell culture systems, particularly in perfusion chambers, to maintain stable oxygen levels without reacting with biological components. Its density and chemical stability make it ideal for use in centrifugation techniques, such as isolating specific cells or embryos in assisted reproductive technologies. Additionally, FC-40 serves as a heat transfer fluid in electronic cooling systems due to its excellent thermal stability and non-conductive nature.
