Overview
Omega™ ultrafiltration membrane disc filters, a Pall Life Sciences product, provides higher flow rates and lower protein binding than regenerated cellulose. They offer high performance and stability for users of conventional, non-disposable ultrafiltration stirred cells.
Polyethersulfone membrane provides higher flow rates and lower protein binding than competitive regenerated cellulose. This results in lower processing times and the highest possible recoveries.
Discs can be washed and reused.
Sanitization
Provided non-sterile. May be sanitized using 200 ppm sodium hypochloride.
Applications
Replacement membranes for other stirred cell systems
Concentration, fractionation, purification, buffer exchange, or desalting of protein, cell broths, and other biomolecules.
