Description
Phosphate-free round filters type MN 619 G with a diameter of 320 mm are specialised cellulose filter papers for laboratory filtration applications that demand media free from phosphate contamination. The large circular discs suit standard filtration setups used under vacuum or gravity and provide generous surface area for higher-volume sample work. Supplied in packs of 100 pc(s) with a pack weight of 0,045 kg, they support ongoing analytical and preparative routines. Positioned among special filter papers, this phosphate-free grade is relevant where residual phosphate would interfere with subsequent determinations, including workflows linked to fat analysis, brewery testing and comparable laboratory separations. The MN 619 G filters from manufacturer MACHEREY-NAGEL combine a clear type designation with a practical 320 mm diameter for consistent handling in funnels and holders common to chemical and environmental laboratories. Users can incorporate the discs into established cellulose filter-paper methods for clarification and sample preparation. The round geometry and defined size help standardise filtration steps across replicate preparations. With 100 units per pack, the product is suited to continuous bench operations that require reliable phosphate-free round filter media.

Questions about Phosphate-free round filters, type MN 619 G, Ø 320 mm, 100 unit(s)
What is this article?
Phosphate-free round filters, type MN 619 G, Ø 320 mm, 100 unit(s) 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.
