Description
Folded filter Fafi MN 651 1/4, 45 cm is a pre-pleated laboratory filter paper designed for gravity filtration and larger-scale clarification work. The 45 cm diameter (450 mm) delivers an extensive filtration surface for funnels and set-ups that accommodate this size, supporting efficient handling of higher liquid volumes. MN 651 1/4 grade filters are supplied already folded, so operators avoid manual creasing and maintain consistent geometry from piece to piece. Packs of 100 non-sterile filters suit analytical, preparative, and quality-control environments that depend on traditional paper filtration. This format from manufacturer Macherey-Nagel retains particulate matter while the filtrate passes under gravity. Pleating increases effective area versus a flat disc of the same diameter, which can assist flow during standard separations. Net weight per pack is 1,67 kg. Use the 45 cm variant when process scale or funnel diameter calls for the largest footprint in this MN 651 1/4 series without altering the filter grade itself.

Questions about Folded Filter Papers MN 651 1/4, 45 cm
What is this article?
Folded Filter Papers MN 651 1/4, 45 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.
