Planova™ was the world’s first virus removal filter when it was launched in 1989. To meet new challenges, Asahi Kasei Bioprocess has developed the newest regenerated cellulose Planova S20N that combines flux and broad adaptability across platforms. As described by the company, the newly developed Planova S20N filters are made from regenerated cellulose hollow fiber membranes. It was designed to improve user-friendly operation while achieving stable filtration over a wide range of solution conditions, inherited from Planova 20N. Planova S20N arrives at your site “ready to use”, with no pre-wetting or sterilization required prior to use in filtration.
