Description
Folded filter MN 704 1/4, 12,5 cm is a pre-pleated laboratory filter paper for gravity filtration of larger sample volumes in chemical, analytical and preparative workflows. Diameter is 12,5 cm (125 mm), offering increased filtration area versus smaller discs while remaining compatible with standard laboratory funnels.
This article is part of Filter paper, in Filtration.
Packs of 100 pieces are supplied from manufacturer Macherey-Nagel in the MN 704 1/4 grade. The Faltenfilter construction arrives already folded, so the cone opens rapidly and seats evenly, supporting steady flow during precipitate recovery, solution clarification and routine clean-up. This format reduces preparation time compared with hand-folding flat sheets and helps maintain consistent geometry from filter to filter.
The 12,5 cm size suits medium-scale filtrations in research, quality control and teaching laboratories. Supply is non-sterile and intended for general technical and chemical use. Net weight per pack is 0,13 kg. Selecting MN 704 1/4 at 12,5 cm supports grade continuity when scaling filtration steps or standardising consumables across multiple benches.

Questions about Folded Filter Papers MN 704 1/4, 12.5 cm
What is this article?
Folded Filter Papers MN 704 1/4, 12.5 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.
