Description
Folded filter MN 675 1/4, 45 cm is a laboratory fluted filter paper for solid–liquid separation and routine clarification of laboratory samples. The filter diameter is 45 cm (450 mm), addressing large-funnel and higher-volume filtration needs in analytical and preparative settings. MN 675 1/4 denotes the familiar fluted, quarter-fold construction that can be seated directly in a funnel without further folding. Each pack holds 100 pieces, providing a convenient quantity for ongoing laboratory use. Filters of this type from manufacturer Macherey-Nagel are offered within the folded-filter category for general laboratory filtration. The ready-folded form simplifies handling and supports consistent presentation of the filtration surface. Net weight of the pack is 3,06 kg, with packaging dimensions that facilitate storage and logistics planning. Supply is non-sterile and intended for standard bench work rather than aseptic procedures. Clear diameter, MN 675 1/4 grade and multi-piece packaging make this item a practical choice for research, quality-control and teaching filtration stations that require a larger 45 cm format.

Questions about Folded Filter Papers MN 675 1/4, 45 cm
What is this article?
Folded Filter Papers MN 675 1/4, 45 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.
