Description
Fluted filter MN 651 1/4, 18,5 cm is a large-format pre-folded filter paper for gravity filtration when higher volume or greater surface area is required. Diameter is 18,5 cm (185 mm); the MN 651 1/4 pleat geometry promotes rapid flow and secure placement in appropriately sized funnels. Packs of 100 pieces support continuous laboratory use in preparative chemistry, environmental sample work-up, and quality-control filtration steps. Pre-fluting eliminates manual folding, saving time and reducing variability between runs. Offered by Macherey-Nagel, this MN 651 1/4 variant is intended for qualitative separations, solids recovery, and clarification tasks where a generous filter diameter improves capacity. Net weight per pack is 0,29 kg. Match the filter to your solvent system and method needs, and handle according to standard laboratory practice. The larger diameter complements smaller MN 651 sizes when scaling filtration volume or funnel type across a method series.

Questions about Folded Filter Papers MN 651 1/4, 18.5 cm
What is this article?
Folded Filter Papers MN 651 1/4, 18.5 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.
