Description
Folded filter MN 620 1/4, 32 cm is a fluted laboratory filter paper intended for routine gravity filtration and sample clarification. It has a diameter of 32 cm (320 mm) and is supplied as the MN 620 1/4 format, giving a ready-to-use cone with increased effective surface area compared with a flat disc of the same grade. Each pack contains 100 pieces, supporting continuous use in analytical, teaching and research laboratories. These filters are from manufacturer Macherey-Nagel and form part of the established MN 620 folded-filter range for general laboratory filtration workflows. The fluted construction helps maintain open flow paths during wet-chemistry work-up, solvent clarification and preparation of solutions prior to further analysis. Matching common large funnel sizes for the stated diameter, the pack is practical for shared lab stocks. Net weight is 0,70 kg per pack. Select this size when a 32 cm MN 620 1/4 folded filter is required for everyday filtration tasks.

Questions about Folded Filter Papers MN 620 1/4, 32 cm
What is this article?
Folded Filter Papers MN 620 1/4, 32 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.
