Product Category Description:
Each of these filtering devices consists of a 50mm size disc for filtering up to 5 liters of media. The AS (Aqueous Solution) devices are non-pyrogenic 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.
The AS with Bell device (28137-870) 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 (28137-868) 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.
Ordering Information: All Polydisc AS devices are radiation sterilized with no ethylene oxide residue contamination. The Polydisc SPF device (28137-868) is nonsterile.
