Cytiva, OM050043, Omega™ ultrafiltration membrane disc filter, 50K MWCO, 43 mm (12/Pk)

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.
