Description
Folded filter MN 619 de 1/4, 45 cm is a laboratory fluted filter paper intended for routine solid–liquid separations and general filtration work. With a diameter of 450 mm, the large circular format suits funnels and filtration setups that handle higher sample volumes while the pre-pleated construction increases effective surface area and supports steady flow. The grade designation MN 619 de 1/4 identifies this Macherey-Nagel folded filter variant for everyday laboratory use. Each pack contains 100 pieces, giving convenient stock for teaching labs, quality-control benches, and preparative workflows. The filters arrive ready to place in the funnel, reducing preparation time compared with flat sheets that must be folded by hand. Typical applications include clarification of suspensions, collection of precipitates, and general sample clean-up where a reliable medium-speed fluted paper is required. Net weight of the pack is 1,83 kg. This format combines a practical diameter with a high piece count for efficient laboratory filtration.

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