Cellulose filter paper is used in qualitative analytical techniques to determine and identify materials. They are "graded" by particle retention and flow rates.

They are available in flat or pre-pleated styles which give improved flow rate and increase loading capacity compared to equivalent flat filters. Multiple sizes and grades are available to fulfill virtually every qualititative analytical filtration need your laboratory may encounter. We carry the brands you lab knows and trusts which include Whatman®, Millipore® Biosciences, Schleicher and Schuell®, Ahlstrom® and others. Choose the brand of your preference to narrow your search.
