Description
Folded filter Fafi MN 651 1/4, 38,5 cm is a pre-pleated laboratory filter paper intended for gravity filtration and routine clarification work. With a diameter of 38,5 cm (385 mm), it provides a generous filtration surface that supports efficient throughput when used with matching funnels and holders. The MN 651 1/4 grade is supplied as ready-to-use folded discs, so manual creasing before use is unnecessary and handling remains consistent from filter to filter. Packs contain 100 pieces and are suitable for analytical and preparative workflows in chemistry, quality control, and general laboratory practice. These non-sterile filters from manufacturer Macherey-Nagel help retain particulate matter while allowing the liquid phase to pass under gravity. The pre-formed pleats increase effective area relative to a flat disc of the same diameter, which can improve flow behaviour during standard separations. Net weight per pack is 1,23 kg. Choose this size when larger funnel diameters or higher sample volumes call for an expanded filter footprint without changing the MN 651 1/4 grade.

Questions about Folded Filter Papers MN 651 1/4, 38.5 cm
What is this article?
Folded Filter Papers MN 651 1/4, 38.5 cm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Filter paper, inside Filtration, in Lab consumables.
Filter paper is a cellulose sheet of a stated retention and speed. Qualitative paper clarifies. Quantitative, ashless paper is for a precipitate that will be weighed or ashed, because the paper itself leaves almost no ash. The diameter has to match the funnel.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
