Description
Filter paper 598 is a qualitative, medium-fast, thick round filter with a basis weight of 140 g/m² and a diameter of 90 mm. Grade 598 combines higher grammage with medium-fast filtration behaviour for qualitative laboratory separations that benefit from a more substantial paper structure. The 90 mm circular format matches common small funnels and sample volumes used in analytical, quality-control, and teaching environments. Supplied in packs of 100 pieces, the filters support standardised handling across series of filtrations. Stated properties focus on the thick construction, 140 g/m² basis weight, and medium-fast speed, suitable for clarifying liquids and retaining precipitates in routine qualitative workflows. This filter paper from manufacturer Hahnemühle is identified by grade, thickness character, diameter, and grammage. Select it when a thick, medium-fast qualitative round filter of 90 mm is specified for everyday laboratory filtration.

Questions about Filter paper 598, qualitative, thick ,medium fast, 140 g/sqm ,Discs 90 mm
What is this article?
Filter paper 598, qualitative, thick ,medium fast, 140 g/sqm ,Discs 90 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.
