Description
Round filter MN 621 is a laboratory round filter paper with a diameter of 50 cm, supplied in convenient packs of 100 pieces. This MN 621 grade filter is intended for standard filtration tasks in analytical, preparative and routine laboratory workflows where a large circular format is required. The 50 cm diameter provides ample surface area for handling larger sample volumes or for use with correspondingly sized funnels and filtration apparatus. Offered by manufacturer Macherey-Nagel, the filters support common separation, clarification and particulate-removal steps in chemistry, life-science and quality-control settings. Each pack contains 100 individual round filters, allowing laboratories to maintain ready stock for continuous experimental or process needs. The circular geometry ensures straightforward placement and even flow distribution during gravity or vacuum-assisted filtration. MN 621 round filters deliver consistent dimensional accuracy and are suitable for everyday wet-chemistry applications that call for reliable, general-purpose filter media in a generous size.

Questions about Round filter MN 621, 50 cm
What is this article?
Round filter MN 621, 50 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.
