Description
Folded filter MN 660 1/4, 40 cm is a laboratory pleated filter (Faltenfilter) with a diameter of 40 cm (400 mm). This MN 660 grade disc is delivered in the ready-folded 1/4 configuration for gravity filtration and everyday sample clarification in analytical, chemical and research settings. Packs contain 100 pieces, supporting continuous laboratory throughput without frequent reordering. The 400 mm diameter fits large funnels commonly used when processing larger sample volumes. Specified as non-sterile, the filter is intended for applications that do not require a sterile barrier. The product comes from manufacturer Macherey-Nagel, whose MN 660 1/4 line spans multiple diameters so laboratories can select the size that matches their glassware and method needs. Pre-folded construction reduces handling steps relative to flat filter circles and helps present a uniform filtration surface. Consistent diameter and pack quantity aid method reproducibility across operators, shifts and instruments. This format belongs to the standard category of qualitative folded filter papers used throughout teaching, quality-control and preparative laboratory environments.

Questions about Folded Filter Papers MN 660 1/4, 40 cm
What is this article?
Folded Filter Papers MN 660 1/4, 40 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.
