Description
Fluted filter MN 618 1/4, 50 cm is a pre-folded laboratory filter paper designed for gravity filtration of larger sample volumes in analytical and preparative settings. At 500 mm diameter, the fluted geometry maximises surface area inside conical funnels and supports steady flow during qualitative separations and clarification steps. Packs of 100 pieces serve teaching laboratories, research groups, and industrial quality-control benches that need a ready supply of consistent filter paper. The MN 618 1/4 grade from manufacturer Macherey-Nagel arrives pre-fluted, reducing preparation time and helping keep filtration channels open once seated. It pairs with standard laboratory glassware and is appropriate for aqueous media and many organic solvents routinely used in wet chemistry. Net weight of the pack is 2,90 kg, indicating a substantial yet manageable bulk unit for facilities with frequent filtration demand. These filters offer a practical consumable for chemistry, life-science, and analytical environments requiring large-diameter fluted paper without complex specification overhead. They support everyday laboratory filtration workflows where reliability and convenient pack size are essential.

Questions about Folded Filter Papers MN 618 1/4, 50 cm
What is this article?
Folded Filter Papers MN 618 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.
