This 16-layer construction is held constant from the laboratory-scale Mustang S XT Acrodisc™ unit to the largest industrial process-scale capsule, ensuring constant chromatography bed depth in all formats. The ease of linear scale-up ensures a shortened process development time by significantly reducing the re-optimization required between scale-up steps. These chromatography products are specifically designed for single-use. This eliminates cleaning and the costs associated with cleaning validation. Mustang capsules are fully self-contained units that connect directly into a system using 18 mm (1.5 in.) sanitary flange connectors.

Mustang™ S membrane

Mustang™ S membrane is cation-exchange support with pendant sulfonic functional groups in a cross-linked polymeric coating on a 0.65 µm pore-size membrane. This gives high dynamic capacities for high molecular weight products such as IgG, Factor VIII, and some viruses.

Features and benefits

Binding efficiency: charged biomolecules are readily bound in a single pass
Speed: high-flow rates enable the processing of large volumes in less than a single working shift. Mustang units typically operate at flow rates between 10 to 40 membrane volumes per minute, making them much faster than conventional columns, which typically operate at 0.5 column volumes per minute.
Scalability: full range of sizes accommodates the different volumes and capacities required in biopharmaceutical processing
Convenience: Ready-to-use, autoclavable, and disposable to eliminate potential packing, cleaning, validation, and cross-contamination issues
Flexible: Available in capsule or cartridge format
Cost: lower operating costs and capital investment compared to conventional columns that need validated packing and cleaning
