Abstract (en)
[origin: WO8503012A1] Charge modified microporous hollow tube filter membranes. The tubes are comprised of an organic polymeric microporous filter membrane having a micro-structure throughout the membrane and an amount of charge modifying agent bound to substantially all of the membrane micro-structure without substantial pore size reduction or pore blockage. The charge modified microporous hollow tubes may be used for the filtration of fluids, particularly parenteral or biological liquids contaminated with charged particulate, and for plasmapheresis and other cross-flow filtration applications. The tubes have low extractables and are sanitizable or sterilizable.
