Description
Round filter MN 619 de with 45 cm diameter is a standard laboratory filtration medium intended for general analytical and preparative work. Supplied in a pack of 100 pieces, it provides a practical quantity for routine filtration tasks in research, quality control and teaching laboratories. The generous 45 cm diameter suits larger funnels and higher-volume separations while maintaining the familiar circular format used throughout classical wet chemistry. Produced by manufacturer Macherey-Nagel, the MN 619 de grade supports everyday gravity filtration for clarifying solutions, collecting precipitates or preparing samples. Each pack has a gross and net weight of 1,81 kg, reflecting the substantial number of filters supplied. These round filters integrate directly into existing protocols without special adapters and offer consistent handling characteristics for repeated daily use. Their straightforward design makes them suitable for a broad range of aqueous and organic solvent applications where reliable particle retention is required. The product meets typical laboratory expectations for qualitative filtration media in standard setups.

Questions about Round filter MN 619 de, 45 cm
What is this article?
Round filter MN 619 de, 45 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.
