Description
Fluted filter Munktell grade 292, 320 mm Ø is designed for normal qualitative-technical filtration of medium-fine crystalline precipitates in the laboratory. The paper combines wet strength with a low ash content of about 0,1 % and a smooth surface that supports clean, reproducible work-up. Typical pore size lies between 5 and 8 µm at a basis weight of 87 g/m². Filtration speed is specified as 50 s/10 ml, with a Herzberg filtration time of 500 s/100 ml (approximately 120 ml/min). Each pack contains 100 pre-pleated filters, offering a large working diameter for higher sample volumes or wider funnels. This Munktell grade 292 format from manufacturer Marienfeld is a practical choice for routine separations where moderate retention, steady flow and convenient funnel loading are needed. The fluted construction increases effective filtration area relative to flat sheets of equal diameter, helping maintain throughput in day-to-day qualitative and technical applications.

Questions about Folded paper filters Munktell grade 292, 320 mm Ø
What is this article?
Folded paper filters Munktell grade 292, 320 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.
