Description
Filter paper 589/4 is a quantitative, medium-fast round filter paper intended for laboratory filtration and analytical sample work. Fat-free and specified at 81 g/m² with a 150 mm diameter, this grade is suited to separations that need reliable sheet behaviour and a larger working area. Type 589/4 is used for quantitative tasks including precipitate recovery, clarification of solutions and preparation of samples for subsequent analysis. Its medium-fast filtration profile balances retention with practical flow, supporting routine chemistry and quality-control applications. The product is supplied as round filters in packs of 100 pieces, matching common funnel sizes for the 150 mm format. Filters from manufacturer Hahnemühle provide consistent grammage and handling characteristics across the pack. The circular 150 mm layout eases positioning and removal during gravimetric and general quantitative procedures. Laboratories seeking fat-free quantitative paper at 81 g/m² can adopt this 589/4 round filter where a 150 mm diameter is required without altering established pack quantities.

Questions about Filter paper 589/4, quantitative ,medium fast, free of fat, 81 g/sqm ,Discs 150
What is this article?
Filter paper 589/4, quantitative ,medium fast, free of fat, 81 g/sqm ,Discs 150 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.
