Description
Folded filter MN 625 1/4, 45 cm is a pre-pleated laboratory filter paper for gravity filtration and related separation work. It offers a diameter of 45 cm (450 mm) and comes in a pack of 100 pieces, making it suitable for high-volume or large-funnel applications and for laboratories that maintain ample filter stock. The quarter-fold (1/4) design expands the effective filtration area compared with a flat disc and allows convenient insertion into conical funnels. The MN 625 1/4 grade from manufacturer Macherey-Nagel is part of an established folded-filter range used across analytical and preparative laboratories. At 45 cm, the format addresses larger vessels and bulkier sample loads where smaller diameters are insufficient. Non-sterile by specification, the filter is intended for general laboratory use, not aseptic procedures. Typical uses cover liquid clarification, precipitate recovery, and sample preparation in chemical, environmental, and quality-control environments. The 100-piece unit quantity aids organised storage and restocking. This MN 625 1/4 folded filter at 45 cm diameter delivers a practical, ready-to-deploy option for routine large-format filtration.

Questions about Folded Filter Papers MN 625 1/4, 45 cm
What is this article?
Folded Filter Papers MN 625 1/4, 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.
