Description
Folded filter MN 619 eh 1/4 is a pre-pleated laboratory filter paper with a diameter of 12,5 cm (125 mm), packed in units of 100 pieces for everyday gravity filtration. The 1/4 fluted design opens rapidly into a stable cone, saving preparation time and promoting even flow relative to hand-folded flat sheets. MN 619 eh grade is suited to general clarification and solid–liquid separation in analytical, preparative and teaching environments. The larger 12,5 cm diameter matches common medium-size funnels and supports moderate sample volumes without frequent filter changes. These folded filters from manufacturer Macherey-Nagel arrive ready to use, helping standardise filtration geometry across replicates. A pack of one hundred filters keeps the bench stocked for continuous workflows while protecting unused papers until needed. Suitable for aqueous media and many mild organic applications where a convenient fluted cellulose filter is preferred over membrane filtration.

Questions about Folded Filter Papers MN 619 eh 1/4, 12.5 cm
What is this article?
Folded Filter Papers MN 619 eh 1/4, 12.5 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.
