Description
Folded filter MN 620 1/4, 38,5 cm is a fluted laboratory filter paper for gravity filtration and routine sample clarification. With a diameter of 38,5 cm (385 mm), the MN 620 1/4 format provides a pre-folded cone and a larger effective filtration area than a comparable flat sheet. Packs contain 100 pieces, which suits regular consumption in analytical, quality-control and research laboratories. The filters are from manufacturer Macherey-Nagel and belong to the MN 620 folded-filter series used for general laboratory filtration. Fluting supports open flow during wet-chemistry work-up, solvent handling and preparation of solutions before downstream steps. The 38,5 cm diameter aligns with larger funnel geometries commonly used for higher sample volumes. Net weight per pack is 1,08 kg. Choose this variant when an MN 620 1/4 folded filter at 38,5 cm is specified for everyday filtration duties.
This article is part of Filter paper, in Filtration.

Questions about Folded Filter Papers MN 620 1/4, 38.5 cm
What is this article?
Folded Filter Papers MN 620 1/4, 38.5 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.
