Description
Fluted filter Munktell grade 6, 185 mm Ø is a qualitative-technical laboratory filter paper intended for routine filtration of medium-fine crystalline precipitates. Its typical pore size of 10–13 µm and smooth surface support reliable particle retention in everyday analytical and technical work. The paper is wet-strength, so it keeps mechanical integrity during wet handling and transfer, while the low ash content of approximately 0,1 % helps limit residue where ignition or ash-related steps matter. Filtration performance is specified at 15 s/10 ml, with a Herzberg filtration time of 70 s/100 ml (about 850 ml/min). Basis weight is 80 g/m². The fluted (pleated) geometry increases effective filtration area versus a flat disc of the same diameter, favouring practical throughput in funnels and related setups. Each pack contains 100 filters in a box and is offered from manufacturer Marienfeld for general qualitative and technical filtration in research, quality-control and teaching laboratories that need a consistent grade-6 medium for medium-fine precipitates.

Questions about Folded paper filters Munktell grade 6, 185 mm Ø
What is this article?
Folded paper filters Munktell grade 6, 185 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.
