Description
Folded filter MN 620 1/4, 9 cm is a pre-pleated laboratory filter paper with a diameter of 9 cm (90 mm), supplied in packs of 100 pieces. The quarter-fold (1/4) design enlarges the effective filtration area and promotes efficient gravity filtration of laboratory liquids. These filters support routine clarification, solids separation and general sample preparation in analytical chemistry, environmental testing and quality-control environments. The 90 mm diameter matches widely used medium-size funnels and filtration set-ups, allowing straightforward integration into existing bench procedures. Non-sterile specification aligns with standard wet-chemistry applications rather than sterile or aseptic work. From manufacturer Macherey-Nagel, MN 620 1/4 folded filters offer a dependable consumable format that reduces handling time compared with flat discs that must be folded manually. Uniform diameter and convenient pack size help laboratories maintain consistent filtration practice across multiple samples. Suitable for research, teaching and industrial QC laboratories that need reliable pre-folded filter papers in everyday volumes.

Questions about Folded Filter Papers MN 620 1/4, 9 cm
What is this article?
Folded Filter Papers MN 620 1/4, 9 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.
