Description
Round filter MN 640 w, 5,5 cm is a laboratory round filter intended for general filtration work in analytical and research environments. With a diameter of 5,5 cm (55 mm), it provides a compact circular format suited to small funnels and routine sample clarification. Each pack contains 100 pieces, supporting continuous laboratory throughput without frequent reordering. The product type is MN 640 w and is offered by manufacturer Macherey-Nagel as a standard round-filter consumable. Net and gross weight are both 0,03 kg per pack, while the packaging volume of 0,000084 m³ keeps storage requirements modest. Packaging height, width and depth are 0,06 m, 0,06 m and 0,03 m respectively, allowing tidy stacking in drawers or cabinets. The filters are supplied non-sterile and are therefore appropriate for everyday chemistry, biology and quality-control applications where sterile conditions are not required. Originating from Germany (Rheinland-Pfalz), this MN 640 w round filter delivers a uniform 5,5 cm diameter for gravity filtration and simple laboratory separation tasks.

Questions about Round filter MN 640 w, 5.5 cm
What is this article?
Round filter MN 640 w, 5.5 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.
