Description
Round filter MN 640 dd, 11 cm is a circular laboratory filter paper intended for routine filtration and sample preparation tasks. With a precise diameter of 11 cm, these filters fit larger standard funnels and support gravity or simple vacuum separations in analytical chemistry, biology and quality-control workflows. Each pack contains 100 pieces, providing a practical quantity for daily laboratory use while the net weight of 0,10 kg keeps storage and handling straightforward. The MN 640 dd grade from manufacturer Macherey-Nagel delivers consistent performance for general clarification, precipitate collection and medium-retention filtration steps. Laboratories appreciate the uniform dimensions that promote reproducible results across parallel experiments and educational settings. The filters are supplied non-sterile and are suitable for a wide range of aqueous and mild organic solvent applications. Compact packaging protects the discs until needed and simplifies inventory management. Whether used in research, teaching or routine testing environments, these round filters contribute to efficient liquid-solid separations and reliable sample processing on a slightly larger scale.

Questions about Round filter MN 640 dd, 11 cm
What is this article?
Round filter MN 640 dd, 11 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.
