Description
Filter paper 598 is a qualitative round filter for medium-fast laboratory filtration. This thick grade has a basis weight of 140 g/m² and a diameter of 110 mm, giving a robust sheet suited to routine gravity filtration and general sample clarification. Grade 598 combines workable flow with the handling strength expected of a heavier qualitative paper, supporting precipitate collection, solution polishing, and preparatory steps ahead of further analysis. The round format fits standard funnels and filtration assemblies used across chemistry, environmental, and teaching laboratories. Produced by manufacturer Hahnemühle, the paper is intended for everyday qualitative work rather than quantitative ash-critical determinations. Each pack contains 100 pieces, which is practical for shared benches and higher sample throughput. Medium-fast filtration behaviour helps keep workflows efficient when processing typical aqueous media and many laboratory solvents under ambient conditions. With its defined grammage, diameter, and qualitative performance profile, filter paper 598 offers a clear specification choice for laboratories standardising on thick, medium-speed round filters.

Questions about Filter paper 598, qualitative, thick ,medium fast, 140 g/sqm ,Discs 110 mm
What is this article?
Filter paper 598, qualitative, thick ,medium fast, 140 g/sqm ,Discs 110 mm is the article on this page. Luminix Health distributes Hahnemühle 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.
