Description
Fluted filter Munktell grade 292, 125 mm Ø is a qualitative-technical laboratory filter paper for routine filtration of medium-fine crystalline precipitates. It offers a smooth surface, wet strength and a low ash content of approximately 0,1 %. Typical pore size is 5–8 µm, supporting consistent particle retention in standard analytical work. Filtration speed is 50 s/10 ml; Herzberg filtration time is 500 s/100 ml, equivalent to about 120 ml/min. Basis weight is 87 g/m². Each pack contains 100 pre-folded filters, ready for use in everyday laboratory and technical filtration where moderate retention and reliable flow are required. The fluted format increases effective surface area and promotes faster throughput than flat discs of the same diameter. These filters from manufacturer Marienfeld suit qualitative workflows that need dependable grade 292 performance without complex preparation, helping laboratories process samples efficiently while maintaining defined retention characteristics.

Questions about Folded paper filters Munktell grade 292, 125 mm Ø
What is this article?
Folded paper filters Munktell grade 292, 125 mm Ø is the article on this page. Luminix Health distributes Marienfeld 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.
