Description
Folded filter MN 619 de 1/4, 40 cm is a qualitative laboratory fluted filter paper supplied in packs of 100 pieces. Each filter has a diameter of 40 cm (400 mm) and is pre-folded into the classic 1/4 pattern that opens quickly into a cone for gravity filtration. The MN 619 de grade is intended for general laboratory separations where a reliable fluted paper is required for clarifying solutions, collecting precipitates or preparing samples ahead of further analysis. With a net weight of 1,41 kg per pack, the filters are convenient to store and dispense at the bench. Produced by manufacturer Macherey-Nagel, these Fafi-style folded filters support routine analytical and preparative workflows in chemistry, environmental and teaching laboratories. The large 40 cm diameter suits bigger funnels and higher-volume filtrations while the pre-pleated construction maximises surface area and flow rate compared with plain circles. Pack size of 100 pieces ensures an economical supply for daily use.

Questions about Folded Filter Papers MN 619 de 1/4, 40 cm
What is this article?
Folded Filter Papers MN 619 de 1/4, 40 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.
