Description
Pleated filter MN 619 G 1/4, 9 cm is a laboratory filter paper supplied in pre-folded form for efficient gravity filtration. The pleated geometry enlarges the usable surface area, which supports reliable flow during clarification of liquids, recovery of precipitates, and general sample preparation. Diameter is 90 mm (9 cm), fitting mid-size funnels commonly used in analytical, process-support, and educational laboratories. Each pack holds 100 pieces, providing a convenient working stock for recurring filtration steps. The MN 619 G 1/4 grade from manufacturer Macherey-Nagel is intended for everyday laboratory filtration where a consistent folded paper filter is preferred over manually creased flat discs. Net weight per pack is 0,08 kg, keeping the unit light and easy to store near the bench. Ready-pleated construction shortens set-up time and helps maintain comparable filtration geometry across parallel samples. These filters are suited to routine solid–liquid separation in aqueous systems and other media compatible with standard cellulose filter paper, supporting clean-up, precipitate collection, and related wet-chemistry operations with straightforward handling.

Questions about Folded Filter Papers MN 619 G 1/4, 9 cm
What is this article?
Folded Filter Papers MN 619 G 1/4, 9 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.
