Made of pure cellulose treated with hydrochloric and hydrofluoric acid, filter paper is quantitative paper used for straining with fast flow rates and good retention. It creates a semi-permeable barrier perpendicular to a liquid or airflow in order to separate fine substances from liquids or air. Different grades of filter paper are available for performing routine laboratory work, ranging from coarse to fine filtration of particulates.
