Description
Folded filter MN 619 eh 1/4 is a laboratory fluted filter paper with a diameter of 15 cm (150 mm), supplied ready for gravity filtration of liquids in analytical and preparative workflows. The pre-folded format increases effective surface area and supports efficient flow when clarifying solutions, separating precipitates or preparing samples prior to further analysis. Each pack contains 100 pieces, making the grade practical for routine bench use in chemistry, quality-control and teaching laboratories. The 150 mm diameter suits standard funnels and filtration setups that require a medium-size folded circle. This folded filter from manufacturer Macherey-Nagel is designated MN 619 eh 1/4 and is intended as a general laboratory filtration consumable rather than a sterile barrier product. Consistent circle size and the fluted geometry help maintain reproducible handling from pack to pack. Laboratories that standardise on Macherey-Nagel filter papers can integrate MN 619 eh 1/4 into everyday clarification and solid–liquid separation steps where a 15 cm folded filter is specified.
This article is part of Filter paper, in Filtration.

Questions about Folded Filter Papers MN 619 eh 1/4, 15 cm
What is this article?
Folded Filter Papers MN 619 eh 1/4, 15 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.
