Filter paper grades depend on the particle retention and the speed of flow. A medium filter speed will generally retain particles that are normally filtered out with fast filtering paper, while still letting the finer particulates pass through the paper during filtration. This particular style of filter paper is Quantitative, meaning that it can help the chemist in determining a numerical amount or percentage of the substances present.

This filter paper is sealed in a cardboard box, containing 100 pieces of 9cm quantitative filter paper.
