Description
Round filter MN 675, 45 cm is a circular laboratory filter paper intended for general filtration duties in analytical and preparative workflows. With a diameter of 45 cm it provides a generous working surface for processing larger sample volumes in gravity or vacuum filtration setups. The filters are supplied in a practical pack of 100 pieces, supporting uninterrupted laboratory routines. MN 675 grade paper is suited to routine clarification, precipitate collection and sample preparation tasks commonly performed in chemistry, biology and environmental laboratories. Available from manufacturer Macherey-Nagel, these round filters fit standard funnels and filtration holders designed for large-diameter media. The non-sterile format is appropriate for applications that do not require aseptic conditions. Consistent material properties help ensure reproducible filtration behaviour across successive uses. The round geometry guarantees even seating and reliable sealing in matching apparatus. Ideal for quality-control, research and teaching laboratories that need dependable, large-format filter paper for everyday separation work.

Questions about Round filter MN 675, 45 cm
What is this article?
Round filter MN 675, 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.
