Description
Round filter MN 85/90, 9 cm is a laboratory round filter paper intended for routine solid–liquid separation in analytical and preparative work. With a diameter of 90 mm, the circular format seats evenly in standard funnels and filtration assemblies used across chemistry, environmental and quality-control laboratories. The MN 85/90 grade from manufacturer Macherey-Nagel is supplied in packs of 100 pieces, providing a practical stock level for everyday sample clarification, qualitative filtration and general laboratory workflows. Non-sterile by specification, these filters suit conventional gravity or simple vacuum filtration rather than aseptic procedures. Their uniform round geometry supports reproducible results when processing multiple samples under identical conditions. The 100-piece pack balances economy with convenient handling, making the product suitable for teaching laboratories, research groups and industrial QC departments that regularly require reliable 9 cm round filter paper. Integration into existing protocols is straightforward, allowing laboratories to maintain consistent filtration performance without altering established methods or glassware setups.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about Glass fiber filters MN 85/90, 9 cm
What is this article?
Glass fiber filters MN 85/90, 9 cm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Glass & quartz fibre filters, inside Filtration, in Lab consumables.
Glass-fibre and quartz-fibre filters are depth filters with a high dirt load, used for air sampling, for total suspended solids and in front of a membrane. They have no sharp pore-size cutoff the way a membrane does. Binderless grades matter when the filter will be weighed or heated.
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.
