Description
Folded filter MN 620 1/4, 40 cm is a fluted laboratory filter paper designed for gravity filtration and everyday sample clarification. It offers a diameter of 40 cm (400 mm) in the MN 620 1/4 folded format, delivering a ready-formed cone with greater effective surface area than a flat disc of the same grade. Each unit is packed as 100 pieces, providing a convenient stock quantity for analytical, teaching and research laboratories. These filters come from manufacturer Macherey-Nagel and are part of the MN 620 folded-filter range for general laboratory use. The fluted structure helps sustain flow during wet-chemistry work-up, clarification of solutions and preparation steps ahead of further analysis. The 40 cm diameter suits larger funnels and higher-volume filtrations. Net weight is 1,06 kg per pack. Select this size when a 40 cm MN 620 1/4 folded filter is required for standard filtration workflows.

Questions about Folded Filter Papers MN 620 1/4, 40 cm
What is this article?
Folded Filter Papers MN 620 1/4, 40 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.
