Description
Folded filter MN 675 1/4, 27 cm is a pre-folded laboratory filter paper for gravity filtration and routine clarification of liquid samples. The filter diameter is 270 mm, offered in the MN 675 1/4 fluted format so the paper can be seated directly in a suitable funnel. Packs contain 100 pieces, providing a convenient working stock for laboratories that run multiple filtrations each day. The pre-formed folds enlarge the effective surface area compared with an equivalent flat disc and help maintain practical flow during standard particulate separation. This size from manufacturer Macherey-Nagel is non-sterile and intended for general analytical and preparative laboratory use rather than sterile processing. Defined diameter and pack layout simplify selection alongside other MN 675 1/4 variants when different funnel sizes are in use. Net and gross weight are each 1,11 kg per pack. Specify this 27 cm folded filter when a ready-to-use MN 675 paper of intermediate diameter is required for everyday sample preparation and wet-chemistry workflows.
This article is part of Filter paper, in Filtration.

Questions about Folded Filter Papers MN 675 1/4, 27 cm
What is this article?
Folded Filter Papers MN 675 1/4, 27 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.
