Combining high capacity, ion-exchange Mustang membranes with a unique 16-layer open-pleat design results in a high-flow rate, high capacity, single-use, versatile range of pleated products that can be used for a wide range of applications.

This 16-layer construction is held constant from the laboratory-scale Mustang XT Acrodisc Unit to the largest industrial process-scale capsule, ensuring constant chromatography bed depth in all formats. Mustang E capsules use three layers of a standard pleat format membrane to remove endotoxin from process feedstreams. The three-layer construction is held constant from the Mustang E Acrodisc® format to the largest industrial process scale capsule.

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 cartridges require the use of a Code 7 housing, which requires cleaning and reassembly after each use. 

Mustang Q Membrane

Mustang Q membrane is anion-exchange support with pendant quaternary amine functional groups in a cross-linked polymeric coating on a 0.8-micron pore-size membrane. This gives high dynamic capacities for high molecular weight products such as DNA, plasmids, or even particles as large as viruses.

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. 

Mustang E Membrane

Mustang E membrane is a highly cross-linked quaternized amine charge polymer coating on a 0.2-micron pore size membrane. This gives very high dynamic capacities under selected conditions for removing the endotoxin from process feedstreams, buffers, and water. 

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
