Description
Folded filter MN 875 1/4 is a pre-pleated laboratory filter paper with a diameter of 450 mm (45 cm), supplied in packs of 100 pieces. The quarter-fold (1/4) design opens quickly for funnel loading and is intended for gravity filtration of larger sample or process volumes that benefit from an extended filtration surface. Applications include routine liquid clarification, preparatory filtration, and qualitative work in analytical, educational, and research settings. The 45 cm working diameter suits larger funnels and higher-volume bench separations while remaining straightforward to handle. Filters of this MN 875 type are produced by Macherey-Nagel and are delivered non-sterile for general laboratory use. Each unit pack holds one hundred folded filters, eliminating the need to crease flat sheets before use. As a member of the folded-filter product group, MN 875 1/4 supports everyday filtration steps that precede more selective techniques or instrumental measurement. Specifying a 450 mm diameter helps laboratories align consumables with matching glassware and protocols.

Questions about Folded Filter Papers MN 875 1/4, 45 cm
What is this article?
Folded Filter Papers MN 875 1/4, 45 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.
