Polydisc Disposable Filter Devices, Whatman
Each of these filtering devices consists of a 50mm size disc for filtering up to 5L of media. The AS (aqueous solution) devices are nonpyrogenic and have a high throughput asymmetric (anisotropic) polyethersulfone membrane, which has low binding and no surfactants. The housings are made of durable polypropylene and come with a sterility cap for easy handling. Stepped hose barb connection. The AS with Bell device provides a high flow rate and up to 50% greater throughput. The filling bell also reduces the risk of contamination during filtration. The SPF device is designed with a unique serial filter stack specifically for serum prefiltration. It contains four layers of special filter media, including fine and ultrafine glass microfiber and a layer of polysulfone. The life of the membrane in all devices is extended with glass microfiber prefilters, which also allow filtration of larger volumes of solution.
