Capsules aid in purification

Open-pore ion-exchange chromatography capsules in a re-usable format have been unveiled by Pall Life Sciences. The Mustang Q XT capsules can be used for high-flow-rate contaminant removal and the removal of large molecules.

The devices feature a polypropylene housing incorporating a chemically-resistant polyethersulfone membrane, which lets them stand up to cleaning, re-use and long-term storage. In addition, process developers can integrate the devices as single-use to avoid cleaning and cleaning revalidation, the company says.

The capsules are available in 5 mL, 140 mL, and 5-liter volumes. Process capacities can be increased by linking units in parallel or series.
