Description
Filter paper 604 is a qualitative, fast laboratory round filter with a basis weight of 79 g/m² and a diameter of 185 mm. Grade 604 supports routine qualitative filtration whenever rapid flow is needed to clarify suspensions or collect coarse precipitates in research, teaching and industrial laboratories. The larger 185 mm circular format suits bigger funnels and higher sample volumes while remaining compatible with standard wet-chemistry filtration setups. Supplied as 100 pieces per pack, the format is convenient for shared laboratory stocks and frequent filtration work. These filters from manufacturer Hahnemühle are defined as product type grade 604, pairing the stated basis weight with a fast filtration profile for everyday qualitative applications. At 79 g/m², the sheet provides a practical compromise between mechanical handling and open structure for quick throughput. Typical uses include general qualitative separations, sample clean-up and preparatory filtration steps where certified quantitative performance is not required. Consistent diameter and basis weight help laboratories maintain reproducible results across chemistry, life-science and quality-control workflows.

Questions about Filter paper 604, qualitative ,fast, 79 g/sqm ,Discs 185 mm
What is this article?
Filter paper 604, qualitative ,fast, 79 g/sqm ,Discs 185 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.
