Description
Folded filter MN 612 1/4, 50 cm, is a qualitative laboratory filter paper supplied as pre-pleated discs for rapid gravity filtration. Each disc has a diameter of 50 cm (500 mm) and is intended for efficient solid–liquid separation in routine analytical and preparative work. The MN 612 1/4 grade from manufacturer Macherey-Nagel is packed in units of 100 pieces, giving a practical stock quantity for busy laboratories. Pre-folded construction increases the effective filtration surface and promotes faster flow compared with flat circles of the same diameter, reducing handling time when clarifying solutions or collecting precipitates. With a pack net weight of 1,73 kg, these large-format papers are ready for immediate use in chemistry, environmental and quality-control laboratories. The 50 cm size suits bulk filtrations and larger sample volumes where smaller standard papers would be impractical. Fafi MN 612 1/4 folded filters support everyday gravity-filtration tasks that rely on dependable cellulose paper media and fit common funnels and filtration stands used across general laboratory workflows.

Questions about Folded Filter Papers MN 612 1/4, 50 cm
What is this article?
Folded Filter Papers MN 612 1/4, 50 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.
