The filter paper is made of pure cellulose treated with hydrochloric acid and hydrofluoric acid and is used for filtration with good retention and flow rate. These cellulose filters create a semi-permeable barrier perpendicular to the liquid or air flow to separate fine matter from the liquid or air. Different grades of filter paper can be used in a variety of laboratory applications, including daily laboratory work, from coarse to fine particle filtration. VWR provides a variety of qualitative and quantitative filter paper with different pore sizes, particle sizes, flow rates and filtration times.
