Description
Folded filter MN 619 eh 1/4 is a pre-pleated laboratory filter paper with a diameter of 24 cm, designed for efficient routine filtration in analytical and preparative work. The MN 619 eh grade delivers reliable particle retention for clarification of aqueous and many organic samples when a large funnel size and high effective surface area are needed. Each pack contains 100 pieces, allowing laboratories to keep a ready supply for continuous sample preparation and quality-control tasks. The pre-folded 1/4 construction expands the filtration area compared with flat sheets of equal diameter and supports faster throughput without manual pleating at the bench. These filters from manufacturer Macherey-Nagel suit general chemistry, life-science and industrial laboratory environments where non-sterile paper filtration is standard practice. With a net weight of 0,46 kg per pack, the product remains practical to store and handle. The 24 cm diameter matches larger funnels used for bulk filtrations, solvent clean-up and preparatory steps before concentration or instrumental analysis.

Questions about Folded Filter Papers MN 619 eh 1/4, 24 cm
What is this article?
Folded Filter Papers MN 619 eh 1/4, 24 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.
