Description
Folded filter MN 675 1/4, 40 cm is a laboratory fluted filter paper intended for solid–liquid separation and everyday sample clarification. With a diameter of 40 cm (400 mm), it fits larger funnels and supports higher-volume filtrations typical of preparative and analytical laboratories. MN 675 1/4 identifies the established fluted, quarter-fold geometry that opens readily in the funnel and is ready for use without additional folding. The product is supplied in packs of 100 pieces, supporting steady laboratory consumption. These filters from manufacturer Macherey-Nagel are part of the folded-filter range for general laboratory filtration duties. The pre-folded format reduces preparation time and helps keep the filtration surface presentation consistent across runs. Diameter and pack size are clearly specified so laboratories can align the item with glassware inventories and workflow planning. The filters are non-sterile and suited to standard bench applications rather than aseptic work. Together, the 40 cm diameter, MN 675 1/4 grade and 100-piece pack form a practical consumable for research, quality-control and teaching environments.

Questions about Folded Filter Papers MN 675 1/4, 40 cm
What is this article?
Folded Filter Papers MN 675 1/4, 40 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.
