Description
Round filter MN 640 dd, 32 cm is a circular laboratory filter paper with a diameter of 32 cm, supplied in convenient packs of 100 pieces. Intended for general filtration duties in analytical and preparative laboratory workflows, these filters from manufacturer Macherey-Nagel deliver consistent performance for routine particle separations. The MN 640 dd grade is well suited to applications that require reliable retention characteristics and steady flow rates across a range of aqueous and organic media. With a pack containing 100 units, the product supports high-throughput environments typical of research, quality-control and teaching laboratories. The generous 32 cm diameter accommodates larger sample volumes and funnels frequently employed in preparative chemistry, environmental analysis and bulk sample processing. Both net and gross pack weight are given as 0,98 kg, facilitating straightforward inventory handling. These round filters integrate smoothly into standard filtration set-ups and provide a practical consumable solution for everyday laboratory separations where reproducible filter performance is required.

Questions about Round filter MN 640 dd, 32 cm
What is this article?
Round filter MN 640 dd, 32 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.
