Description
Filter paper 589/4 is a quantitative round filter engineered for medium-fast filtration in laboratory workflows. Grade 589/4 is specified as fat-free, with a basis weight of 81 g/m² and a compact circular diameter of 90 mm, making it well suited to smaller funnels and routine analytical separations. The medium-fast filtration behaviour balances throughput with retention, supporting precipitate collection, sample clarification, and general quantitative work where a quicker flow than slow grades is advantageous. Each pack supplies 100 round filters for consistent day-to-day use. Product type 589/4 from manufacturer Hahnemühle is intended for quantitative filtration applications and is not described as a sterile product. Defined grammage, fat-free character, and a precise 90 mm format help laboratories standardise handling and method setup. Choose this medium-fast quantitative filter paper when you need a fat-free sheet, controlled 81 g/m² weight, and a practical small-diameter round filter for everyday analytical filtration.

What is this article?
Filter paper 589/4, quantitative ,medium fast, free of fat, 81 g/sqm ,Discs 90 m 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.
