Description
Fluted filter MN 619 1/4, 5,5 cm is a pre-folded laboratory filter paper intended for routine gravity filtration of liquids in analytical and preparative workflows. With a diameter of 55 mm (5,5 cm), the fluted geometry increases the effective surface area and supports rapid flow while the paper remains seated in a funnel. The MN 619 1/4 grade is supplied as a ready-to-use fluted disc, reducing preparation time compared with hand-folding flat sheets. Each pack contains 100 pieces, suitable for series work in chemistry, environmental, food, and quality-control laboratories. These filters from manufacturer Macherey-Nagel are non-sterile and are intended for general laboratory filtration rather than sterile or aseptic applications. The compact 5,5 cm format fits smaller funnels and sample volumes where a full-size fluted paper would be oversized. Consistent diameter and fold pattern help standardise filtration steps across batches. Use for clarifying solutions, removing precipitates, or preparing filtrates ahead of further analysis, always matching paper grade and pore characteristics to the specific method requirements of your laboratory.

Questions about Folded Filter Papers MN 619 1/4, 5.5 cm
What is this article?
Folded Filter Papers MN 619 1/4, 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.
