Description
MN 612 1/4 folded filter is a pre-pleated filter paper with a diameter of 24 cm (240 mm), ready for gravity filtration in conical funnels. Each pack contains 100 pieces, giving laboratories a practical stock level for routine analytical and preparative work. Pre-folding increases the effective filtration area and supports faster throughput than flat circles of the same diameter, while the MN 612 grade is suited to general clarification and solid–liquid separation. Manufactured by Macherey-Nagel, the Fafi MN 612 1/4 series is widely applied in sample preparation, precipitate recovery and everyday laboratory filtration. The 24 cm format fits larger funnels common in preparative chemistry, teaching labs and quality-control environments. Consistent paper quality and precise pleating help maintain reproducible flow behaviour from sheet to sheet. These disposable filters reduce cleaning effort versus reusable media and integrate smoothly into standard funnel workflows. Suitable for research, industrial and educational settings that need dependable folded filter paper in a convenient multipack.

Questions about Folded Filter Papers MN 612 1/4, 24 cm
What is this article?
Folded Filter Papers MN 612 1/4, 24 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.
