Düsseldorf/Germany — Virus removal filters are used to enhance safety in the production process for biotherapeutic products such as biopharmaceuticals and plasma derivatives. Asahi Kasei Medical's Planova cellulose membrane filters, which were launched in 1989 have been developed specifically for removing viruses from biotherapeutic products. Planova Bio EX hydrophilic PVDF (polyvinylidene fluoride) membrane filters provide viral clearance in high protein concentration solutions.

With heightened standards throughout the world for the viral safety of biotherapeutics and advances in the development of monoclonal antibodies and other biopharmaceuticals, the company expects global demand for Planova filters to continue on growing. According to the manufacturer, the new spinning plant will enable them to maintain stable product supply and meet rising demand. Together with a spinning plant for Planova Bio EX filters completed in Oita, Japan, in 2016, the new spinning plant announced recently will increase total production capacity for hollow-fiber virus removal membranes to 130,000 m2/year.
