Description
Folded filter MN 619 de 1/4, 50 cm is a large-format laboratory fluted filter paper for solid–liquid separations and general filtration tasks. The 500 mm diameter provides ample surface area for higher-volume samples and larger funnels, while the pre-folded construction promotes efficient flow and easy placement in the filtration assembly. MN 619 de 1/4 denotes this Macherey-Nagel folded filter grade for routine laboratory practice. Supplied in packs of 100 pieces, the product supports continuous use in analytical, preparative, and teaching environments without frequent reordering. Ready-to-use pleats save time versus hand-folding flat sheets and help maintain consistent filtration geometry from piece to piece. Common uses include clarification of suspensions, recovery of precipitates, and sample preparation steps that benefit from a dependable fluted medium. Pack net weight is 2,24 kg. The combination of generous diameter and multi-piece packaging makes this filter a practical choice for high-throughput or large-volume filtration work.

Questions about Folded Filter Papers MN 619 de 1/4, 50 cm
What is this article?
Folded Filter Papers MN 619 de 1/4, 50 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.
