Description
Round filter MN 621, 38,5 cm is a large-diameter circular laboratory filter paper for solid-liquid separation and sample clarification. Measuring 38,5 cm across, it accommodates high-volume funnels and filtration assemblies used in preparative chemistry, environmental analysis and industrial quality-control laboratories. Each pack holds 100 pieces, enabling efficient handling of multiple samples or larger batch filtrations. The MN 621 grade from manufacturer Macherey-Nagel offers dependable performance for routine gravity and vacuum filtration applications. Non-sterile construction suits non-aseptic laboratory processes in research, teaching and production support settings. The generous diameter reduces the need for multiple smaller filters when processing bulk solutions or collecting substantial precipitates. Uniform circular geometry promotes easy placement and reliable contact with funnel walls. These round filters serve as a practical consumable for classical wet-chemistry workflows, sample clean-up and general laboratory filtration, helping maintain smooth sample-preparation routines with consistent format and convenient pack quantity.

Questions about Round filter MN 621, 38.5 cm
What is this article?
Round filter MN 621, 38.5 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.
