Description
Fluted filter MN 619 1/4, 24 cm is a pre-folded laboratory filter paper for gravity filtration and everyday solid–liquid separations. Its 24 cm diameter (240 mm) provides a generous filtration area that fits larger funnels and supports efficient throughput when clarifying suspensions, collecting precipitates or polishing solvents. Supplied in a pack of 100 pieces, the format offers convenient replenishment for busy analytical, preparative and quality-control laboratories. The MN 619 1/4 grade from manufacturer Macherey-Nagel is part of a well-known line of fluted filter papers designed for straightforward bench use. Ready-formed flutes eliminate manual folding, helping operators start filtrations quickly and with consistent geometry from sheet to sheet. The pack net weight is 0,41 kg, reflecting a practical quantity for routine stock. Uniform diameter and fold pattern contribute to predictable flow behaviour during standard laboratory procedures. These filters are suitable for clarifying reaction mixtures, recovering crystalline material and preparing samples prior to further processing or measurement, supporting reliable day-to-day filtration workflows without extra preparation steps.

Questions about Folded Filter Papers MN 619 1/4, 24 cm
What is this article?
Folded Filter Papers MN 619 1/4, 24 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.
