Description
Folded filter MN 619 eh 1/4, 50 cm is a laboratory fluted filter paper intended for gravity filtration of larger sample volumes. The filter diameter is 50 cm (500 mm), so the quarter-fold presentation fits wide funnels while the pleated structure enlarges the active filtration area and promotes consistent flow. Supplied as a pack of 100 pieces, it supports continuous laboratory demand for clarification, precipitate recovery and routine solid–liquid separation. Manufactured by Macherey-Nagel, the MN 619 eh 1/4 grade is a well-known choice for general analytical and preparative applications where non-sterile media are appropriate. Net weight of the pack is 1,87 kg. The 50 cm size extends capacity for higher-volume work without altering the familiar filter designation, making these folded filters a practical consumable for research, process and quality-control environments that rely on standard glassware and filtration assemblies.

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