Description
Fluted filter Munktell grade 6, 125 mm diameter, is designed for normal qualitative-technical filtration of medium-fine crystalline precipitates. The paper combines a smooth surface with wet strength and a low ash content of about 0,1 %, supporting clean handling in routine laboratory separations. Typical pore size lies between 10 and 13 µm, and the basis weight is 80 g/m². Filtration speed is 15 s/10 ml, with a Herzberg filtration time of 70 s/100 ml, equivalent to approximately 850 ml/min, giving comparatively rapid flow while retaining medium-fine solids. These characteristics suit everyday qualitative work where balanced retention and throughput are needed. Each pack contains 100 filters and is offered by manufacturer Marienfeld, with the fluted construction increasing usable surface area for efficient funnel filtration in chemical, teaching and quality-control environments.

Questions about Folded paper filters Munktell grade 6, 125 mm Ø
What is this article?
Folded paper filters Munktell grade 6, 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.
