High performance and stability for users of conventional, non-disposable stirred cells
- Polyethersulfone membrane provides higher flow rates and is lower protein binding than competitive regenerated cellulose. This results in lower processing time and the highest possible recoveries.
- Discs can be washed and reused up to 20 times.
- Large selection of MWCOs and pore sizes for a variety of applications.
- Diameters from 25 to 150 mm fit various-size systems.
- Broad chemical compatibility over pHs from 1 to 14.
- Replacement membranes for other stirred cell systems.
- Concentration, fractionation, purification, buffer exchange, or desalting of protein, cell broths, and other biomolecules.
- Bench or pilot separations prior to scale up.
