Description
Filter paper 591, qualitative, medium fast, 161 g/m², 580 × 580 mm is a laboratory sheet filter intended for qualitative separations where a balanced, medium-fast flow rate is required. Grade 591 combines a basis weight of 161 g/m² with generous sheet dimensions of 580 × 580 mm, giving ample working area for folding, cutting, or use as large-format filter sheets on the bench. The medium-fast filtration behaviour suits routine clarification and qualitative analytical work in chemistry, life-science, and teaching laboratories. Sheets can also serve as protective underlays or cover papers where a robust cellulose surface is needed. Manufactured by Hahnemühle, this qualitative filter paper is supplied in packs of 100 pieces, supporting high-throughput sample preparation and general laboratory stock. The defined grammage and format help ensure consistent handling from sheet to sheet. Choose grade 591 when medium retention speed and large sheet size are preferred for everyday filtration and bench-protection tasks without additional performance claims beyond the stated qualitative, medium-fast character and physical dimensions.

Questions about Filter paper 591, qualitative ,medium fast, 161 g/sqm ,580 x 580 mm
What is this article?
Filter paper 591, qualitative ,medium fast, 161 g/sqm ,580 x 580 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.
