Description
Folded filter MN 619 de 1/4, 11 cm is a pre-pleated laboratory filter paper designed for gravity filtration and reliable solid–liquid separation. The 110 mm diameter matches common medium funnel sizes and provides ample surface area for efficient throughput in analytical and preparative procedures. Supplied in the MN 619 de 1/4 quarter-fold format, each filter forms a ready-to-use cone that can be placed directly into the funnel without extra folding. Packs contain 100 pieces with a net weight of 0,12 kg, giving laboratories a convenient quantity for daily bench work. This folded filter from manufacturer Macherey-Nagel supports routine applications including clarification of solutions, retention of precipitates and general sample preparation in chemistry and quality-control settings. The product is non-sterile and appropriate where sterile filtration is not required. Uniform diameter and pleat geometry promote consistent seating and reproducible filtration behaviour from run to run. For laboratories needing a practical 11 cm fluted paper filter, the MN 619 de 1/4 pack offers a clear, ready-to-deploy option for standard workflows.

Questions about Folded Filter Papers MN 619 de 1/4, 11 cm
What is this article?
Folded Filter Papers MN 619 de 1/4, 11 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.
