Microclar filter papers are tailored to meet the filtration needs of analytical methods for performing physicochemical and gravimetric analyses. They are manufactured in a strictly controlled environment to ensure uniformity and a high level of purity. This line has been developed for use in analytical methods. They enable the determination and identification of suspended particles in a liquid, regardless of the quantity present.

Their qualities ensure proper particle retention, filtration speed, loading capacity, and wet strength.
