Description
Pleated filter MN 611 1/4, 45 cm is a folded laboratory filter intended for gravity filtration and general sample preparation. Measuring 450 mm in diameter, it offers a large filtration area suited to higher-volume liquids and larger funnels commonly found in analytical and teaching laboratories. The pre-pleated MN 611 1/4 construction eases placement on support funnels and helps keep the filter open during use. Each unit is supplied in a pack of 100 pieces, which supports continuous bench work and straightforward stock replenishment. These filters from manufacturer Macherey-Nagel form part of the established MN 611 range and are specified as non-sterile. The 1/4 designation refers to the quarter-fold pleated format widely used in wet-chemistry workflows. Laboratories choose the 45 cm size when a generous working diameter is required for clarification or particulate retention steps. The article is not marked for dual-use control and is intended for standard laboratory filtration practice. Consistent packaging of 100 filters per pack simplifies inventory planning across multi-user facilities and routine qualitative filtration setups.

Questions about Folded Filter Papers MN 611 1/4, 45 cm
What is this article?
Folded Filter Papers MN 611 1/4, 45 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.
