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.

Qualitative Filter Papers, Wet Strengthened Grades, Whatman
Supplier: Cytiva
These extremely strong filter papers have a high wet strength due to the addition of a small quantity of chemically stable resin. Normal qualitative applications will not introduce any significant impurities into the filtrate. The resins do, however, contain nitrogen so these grades should not be used in Kjeldahl estimations.
