Description
Folded filter MN 675 1/4, 50 cm is a laboratory fluted filter paper intended for gravity filtration and routine sample preparation. With a diameter of 50 cm (500 mm), the large format suits funnels and setups that handle higher sample volumes in analytical, environmental, and quality-control work. The pre-folded MN 675 1/4 construction increases effective surface area and supports steady flow when separating precipitates or particulate matter from liquids. Packs contain 100 pieces, giving laboratories a practical stock quantity for repeated daily use without frequent reordering. These filters from manufacturer Macherey-Nagel integrate easily into standard wet-chemistry workflows where consistent paper media and reliable pack sizes matter. The fluted geometry reduces the need for manual folding at the bench and helps maintain uniform contact with the funnel wall. Suitable for general laboratory filtration tasks that call for a robust, large-diameter folded paper grade rather than membrane or specialty media.

Questions about Folded Filter Papers MN 675 1/4, 50 cm
What is this article?
Folded Filter Papers MN 675 1/4, 50 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.
