High-Performance Single-Use Bags for Critical Bioprocessing- EZBio® Ultra Bag Assembly
The EZBio® Ultra Bag Assembly is a high-performance single-use solution developed for reliable fluid storage and transfer in demanding bioprocessing workflows. Designed to support consistency, sterility, and throughput, these bag assemblies are engineered to minimize hold-up volume while maintaining strong mechanical integrity and predictable flow behavior.
Built for both upstream and downstream applications, EZBio® Ultra Bags provide a dependable option for handling buffers, media, and process fluids where contamination control and material performance are essential.
The EZBio® Ultra Bag Assembly is a made-to-order single-use bag system constructed from medical-grade Renolit 9101 multilayer polyethylene film. This film offers high clarity, excellent strength, and low permeability to oxygen and carbon dioxide, supporting stable storage and transfer of sensitive bioprocess fluids.
Each bag features ports engineered for enhanced edge-seal integrity, improving flow performance while reducing fluid hold-up. This design enables consistent and repeatable transfer, especially in high-throughput operations where product recovery is critical.
EZBio® Ultra Bags are supplied as fully assembled, double-bagged, and gamma-sterilized systems. Customers can select tubing brands and fitting configurations from Foxx Life Sciences’ standard options, ensuring compatibility with existing processes. Assemblies are manufactured in the United States and typically delivered within four to six weeks.
