Description
Folded filter MN 619 de 1/4, 5,5 cm is a pleated laboratory filter paper for routine solid–liquid separation. The diameter is 5,5 cm, corresponding to 55 mm, and matches common small funnel formats used in analytical and preparatory work. Filters are packed in units of 100 pieces, providing a practical stock quantity for everyday laboratory filtration. The folded construction increases effective surface area compared with a flat disc of the same diameter and simplifies seating in the funnel. This MN 619 de 1/4 type is offered by manufacturer Macherey-Nagel within its range of laboratory filtration media. Pack net weight is 0,05 kg, with compact packaging that supports tidy storage on the bench or in consumable cabinets. These pre-folded papers are intended for sample clarification and general filtration steps where a 5,5 cm pleated filter is specified. They fit standard workflows in the folded-filter category without requiring additional shaping before use.

Questions about Folded Filter Papers MN 619 de 1/4, 5.5 cm
What is this article?
Folded Filter Papers MN 619 de 1/4, 5.5 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.
