Description
Folded filter MN 625 1/4, 38,5 cm is a pre-pleated laboratory filter paper for gravity filtration and routine separation work. It has a diameter of 38,5 cm (385 mm) and is supplied in a pack of 100 pieces, supporting laboratories that run multiple filtrations or keep consumables in stock. The quarter-fold (1/4) construction enlarges the effective surface relative to a flat disc of the same diameter and eases placement in conical funnels. From manufacturer Macherey-Nagel, the MN 625 1/4 grade belongs to a well-known folded-filter series used in analytical and preparative settings. The 38,5 cm size suits larger funnels and higher-volume steps where smaller papers are inadequate. Specified as non-sterile, it is intended for general laboratory use rather than aseptic work. Typical tasks include clarification, precipitate collection, and sample clean-up in chemical, environmental, and quality-control laboratories. The 100-piece pack supports orderly storage and replenishment. Overall, this MN 625 1/4 folded filter offers a practical, ready-to-use option for everyday filtration at 38,5 cm diameter.

Questions about Folded Filter Papers MN 625 1/4, 38.5 cm
What is this article?
Folded Filter Papers MN 625 1/4, 38.5 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.
