Filter paper chemistry function.

Fluted filter paper has an increase of the filter area. The mixture is poured from above onto a filter medium e g filter paper and gravity pulls the liquid down. The raw materials are different paper pulps the pulp may be from softwood hardwood fiber crops mineral fibers for high quality filters dissolving pulp and mercerised pulp are used. Composed of cellulose fiber these filters are manufactured from high quality cotton linters treated to maximize alpha cellulose.

The gaps provide channels for the solvent to flow. Most filter papers are made on small paper machines for laboratory filters the machines may be as small as 50 cm width. Used around the world in laboratories to assay sugar cane or beet. It also creates gaps between the filter paper and the funnel in which it is resting.

There are a vast range of applications in and out of the laboratory. F1091 grade very fast filtration. The paper is often crêped to improve porosity. The solid is left on the filter while the liquid flows below it.

These filters are not recommended for kjeldahl estimations. Fluted filter paper has an increase of the filter area. Crêped surface filter paper with medium flow rate. For general laboratory use in less critical analyses.
