Description
Folded filter MN 619 eh 1/4, 45 cm is a laboratory fluted filter paper for efficient gravity filtration in analytical and preparative work. With a diameter of 45 cm (450 mm), the quarter-fold format seats quickly in standard funnels while the pleated geometry increases effective surface area and supports steady flow during solid–liquid separation. Each pack contains 100 pieces, giving laboratories a practical stock level for routine clarification, precipitate collection and sample clean-up. The MN 619 eh 1/4 grade from manufacturer Macherey-Nagel is a familiar consumable on chemistry, environmental and quality-control benches where non-sterile filter media are specified. The larger diameter suits wider funnels and higher sample volumes without changing the established filter designation. Ready for immediate use in common glassware and filtration assemblies, these folded filters help maintain reproducible day-to-day workflows whenever a dependable MN 619 eh 1/4 medium in the 45 cm size is required.
This article is part of Filter paper, in Filtration.

Questions about Folded Filter Papers MN 619 eh 1/4, 45 cm
What is this article?
Folded Filter Papers MN 619 eh 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.
