Description
Filter paper 589/4 is a quantitative, medium-fast round filter paper for laboratory solid–liquid separations. It is fat-free, has a basis weight of 81 g/m² and a diameter of 125 mm, making it suitable for analytical work where controlled filtration behaviour and clean handling matter. Grade 589/4 supports quantitative routines such as precipitate collection, solution clarification and sample preparation ahead of further measurement. The medium-fast filtration character offers a practical balance between retention and throughput in everyday chemistry and quality-control workflows. These round filters are supplied in packs of 100 pieces and fit standard funnel and filtration assemblies used with the 125 mm format. Consistent sheet properties from manufacturer Hahnemühle help maintain reproducible handling from filter to filter. The circular geometry simplifies placement, wetting and removal during gravimetric and general quantitative procedures. Laboratories can integrate this 589/4 grade into established methods that call for fat-free quantitative paper at 81 g/m² without changing familiar pack formats or diameters.

Questions about Filter paper 589/4, quantitative ,medium fast, free of fat, 81 g/sqm ,Discs 125
What is this article?
Filter paper 589/4, quantitative ,medium fast, free of fat, 81 g/sqm ,Discs 125 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.
