Description
Folded filter MN 620 1/4, 27 cm is a pre-fluted laboratory filter paper designed for gravity filtration and routine solid–liquid separation. The 27 cm diameter (270 mm) provides a generous filtration area for larger sample volumes and faster throughput in funnels of matching size. Each pack holds 100 pieces, giving a practical stock level for busy analytical, teaching and quality-control laboratories. The filters are non-sterile and intended for general chemical and preparative work rather than sterile applications. Pack data list a net weight of 0,50 kg for the complete unit. Supplied by manufacturer Macherey-Nagel, the MN 620 1/4 fold pattern opens readily and seats evenly, reducing preparation time versus hand-pleating flat sheets. Typical uses include clarification, precipitate collection and solvent filtration where a consistent fluted geometry improves flow and handling. Select this diameter when your funnel and batch size call for the larger 27 cm format within the MN 620 1/4 series.

Questions about Folded Filter Papers MN 620 1/4, 27 cm
What is this article?
Folded Filter Papers MN 620 1/4, 27 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.
