Description
Folded filter MN 619 de 1/4, 7 cm is a pleated laboratory filter paper intended for routine filtration tasks. The diameter is 7 cm, equivalent to 70 mm, and suits standard funnel sizes used for sample preparation and clarification. Each pack contains 100 pieces, offering a convenient working quantity for daily laboratory use. The pre-folded design enlarges the effective filtration surface relative to a flat circle of the same diameter and allows quick placement in the funnel without manual pleating. This MN 619 de 1/4 grade comes from manufacturer Macherey-Nagel as part of its laboratory filter paper portfolio. Pack net weight is 0,07 kg, and the compact pack format supports efficient storage alongside other consumables. These filters serve general solid–liquid separation and sample clean-up steps where a 7 cm folded paper is required. They integrate directly into standard folded-filter workflows in analytical and quality-control laboratories.

Questions about Folded Filter Papers MN 619 de 1/4, 7 cm
What is this article?
Folded Filter Papers MN 619 de 1/4, 7 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.
