Description
Folded filter MN 620 1/4, 12,5 cm is a pre-pleated laboratory filter paper for routine gravity filtration and sample clarification. It has a diameter of 12,5 cm (125 mm) and is supplied in the MN 620 1/4 format, giving a ready-to-use quarter-folded profile that seats cleanly in standard funnels. The pack contains 100 pieces, supporting continuous bench work without frequent reordering. These filters from manufacturer Macherey-Nagel are non-sterile consumables intended for general laboratory filtration of liquids where a reliable folded paper grade is required. The pleated construction increases the effective surface area relative to a flat disc of the same diameter, which can improve flow under gravity. With a net weight of 0,12 kg per pack, the unit is easy to store and handle in stockrooms or on the bench. This 12,5 cm MN 620 1/4 folded filter suits analytical, teaching and research laboratories that need consistent everyday filtration media in a practical multi-piece pack for aqueous and organic sample work.

Questions about Folded Filter Papers MN 620 1/4, 12.5 cm
What is this article?
Folded Filter Papers MN 620 1/4, 12.5 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.
