Description
Folded filter MN 675 1/4, 18,5 cm is a pre-pleated laboratory filter paper with a diameter of 18,5 cm (185 mm) for gravity filtration of larger sample volumes. The MN 675 1/4 fold pattern presents a high effective surface area in the funnel, which supports efficient flow while the paper remains easy to position and wet evenly during routine clarification or solids collection.
This article is part of Filter paper, in Filtration.
Packs contain 100 filters, suited to laboratories that run frequent filtrations and prefer ready-folded cones instead of hand-folding flat sheets. The product is non-sterile and intended for standard chemical and analytical laboratory practice. These folded filters from manufacturer Macherey-Nagel follow the established MN 675 1/4 specification, giving users a consistent format across different diameters in the same grade family.
Net weight is 0,59 kg per pack. Choose the 18,5 cm size when working with larger funnels so the pleated cone seats correctly and utilises the full filtration area. The combination of defined diameter, pre-folded construction and bulk pack quantity supports dependable, time-saving filtration workflows at the bench without extra preparation steps.

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.
