Description
Folded filter MN 621 1/4, 15 cm is a pre-folded laboratory filter paper for routine filtration tasks in research, teaching and industrial labs. It has a diameter of 15 cm (150 mm) and belongs to the MN 621 1/4 grade in the folded-filter range. Each pack contains 100 pieces, so sheets are ready for the funnel without manual folding at the bench. The filters are non-sterile and intended for work where sterile media are not required. Pack data include a net weight of 0,31 kg and a gross weight of 0,31 kg, with a compact carton suited to orderly shelf storage. This item comes from manufacturer Macherey-Nagel as part of its laboratory filtration consumables. The 15 cm size matches common funnel diameters and typical sample volumes used in clarification and general solid–liquid separation. Uniform diameter and fold style support consistent handling across users and workstations, while the MN 621 1/4 designation keeps grade identity clear in inventory and method documentation.

Questions about Folded Filter Papers MN 621 1/4, 15 cm
What is this article?
Folded Filter Papers MN 621 1/4, 15 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.
