Description
Folded filter MN 620 1/4, 18,5 cm is a pre-pleated laboratory filter paper intended for gravity filtration and sample clarification at a larger disc size. It measures 18,5 cm in diameter (185 mm) and is supplied in the MN 620 1/4 folded format for direct use in matching funnels and filtration assemblies. Packs contain 100 pieces, supporting continuous laboratory supply for routine workflows. These filters from manufacturer Macherey-Nagel are non-sterile consumables for general laboratory filtration of liquids. The pleated design increases effective filtration surface area versus a flat disc of equal diameter, which helps maintain flow under gravity when processing larger volumes or broader funnel geometries. Each pack has a net weight of 0,23 kg for convenient storage and bench handling. Research, teaching and analytical laboratories that rely on MN 620 1/4 media can deploy this 18,5 cm size for everyday clarification and preparation work where a larger folded filter paper is required in a practical 100-piece pack.
This article is part of Filter paper, in Filtration.

Questions about Folded Filter Papers MN 620 1/4, 18.5 cm
What is this article?
Folded Filter Papers MN 620 1/4, 18.5 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.
