Description
Round filter MN 611, 45 cm is a circular laboratory filter paper supplied for general filtration tasks that require a large working diameter. The MN 611 grade designation identifies the filter type within the familiar Macherey-Nagel range, while the 45 cm diameter provides ample surface area for collecting precipitates, clarifying solutions or supporting gravity and simple vacuum filtration on correspondingly large funnels. Each pack contains 100 pieces, making the format practical for routine sample preparation, teaching laboratories and production-support workflows where consistent filter dimensions are needed from batch to batch. These round filters from manufacturer Macherey-Nagel are intended for everyday laboratory use and fit standard large-diameter filter holders and funnels without trimming. The plain circular geometry allows straightforward placement and folding when a fluted or multi-fold configuration is preferred. With a defined diameter of 45 cm and a convenient 100-piece pack, the MN 611 round filter supports efficient stock management and reproducible filtration setups across analytical, preparative and educational environments that rely on classic paper-based separation techniques.

Questions about Round filter MN 611, 45 cm
What is this article?
Round filter MN 611, 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.
