Description
Round filter MN 621, 45 cm is a large-diameter laboratory round filter intended for filtration of bigger sample volumes or bulkier precipitates. The 45 cm diameter offers extended surface area that suits preparative work, industrial quality checks and teaching laboratories handling substantial liquid quantities. Supplied in packs of 100 pieces, the MN 621 grade filters provide ample stock for repeated use across multiple experiments or production batches. These non-sterile round filters originate from manufacturer Macherey-Nagel and are manufactured in Germany. They integrate easily into standard funnel systems and filtration apparatus commonly found in chemical, environmental and materials laboratories. The generous diameter reduces the need for multiple smaller filters when processing larger volumes, thereby streamlining workflow. Consistent sizing supports reproducible results in routine clarification, residue collection and solid-liquid separation steps. Laboratories value the practical pack format that keeps essential filtration media readily available. The MN 621 series remains a straightforward choice for everyday filtration needs where reliability and ease of handling matter most. This 45 cm version extends the range for users requiring greater capacity without changing established procedures.

Questions about Round filter MN 621, 45 cm
What is this article?
Round filter MN 621, 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.
