Description
Round filter MN 615 with a diameter of 40 cm is a laboratory round filter paper intended for general filtration duties in analytical and preparative chemistry. These circular filters measure 40 cm across and are supplied in packs of 100 pieces, making them practical for high-throughput environments or teaching laboratories that consume filter media regularly. The MN 615 series from manufacturer Macherey-Nagel is widely used for qualitative separations of precipitates and clarification of solutions during chemical analysis. Non-sterile by design, the filters suit standard wet-chemistry procedures rather than aseptic work. Their large diameter accommodates bigger sample volumes and larger funnels commonly found in preparative settings. Each pack has a net weight of 0,98 kg and originates from Germany. Researchers, technicians and educators rely on these round filters for routine sample preparation, educational demonstrations and quality-control filtration steps where consistent paper performance is essential. The straightforward circular format simplifies storage and dispensing while supporting reproducible laboratory workflows across chemistry, biology and environmental testing disciplines.

Questions about Round filter MN 615, 40 cm
What is this article?
Round filter MN 615, 40 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.
