Device volume of < 1 mL minimizes sample volume requirements 16 layers of Mustang membrane allows easy scale up to Mustang membrane pilot and process scale capsules. Units achieve flow rates of up to 10 membrane volumes per minute (MV) without affecting performance. Female Luer lock inlet and outlet simplifies use with typical low pressure chromatography systems. Mustang XT Acrodisc units, available in Q and S chemistries, are ideal for scale down process development work in a variety of downstream process applications. Mustang Q Membrane Mustang Q membrane is an ion exchange support with pendant quaternary amine functional groups in a crosslinked polymeric coating on a 0.8micron poresize 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 poresize membrane. This gives high dynamic capacities for high molecular weight products such as IgG, Factor VIII, and some viruses.
