• Available with different pore size membranes
• 90% typical recovery and low hold-up volume
• PP housing minimises non-specific protein binding

Applications includes concentration and desalting of chromatography column eluates, concentrating monoclonal antibodies, concentrating proteins or viruses from culture supernatants, clarifying tissue homogenates and lysates, buffer exchange or diafiltration.
