Description
Filter paper 604 is a qualitative round filter designed for fast filtration in routine laboratory applications. With a basis weight of 79 g/m² and a compact 55 mm diameter, grade 604 supports rapid separation of coarser precipitates and quick clarification steps where throughput is important. Its fast-filtering character suits preparatory work, simple qualitative checks, and small-volume samples that do not require a dense, slow paper. The circular format fits small funnels and standard bench filtration setups used in analytical, educational, and quality-control environments. Supplied in packs of 100 pieces, it is practical for high-frequency use and easy stock management. Grade 604 is offered by Hahnemühle as part of its qualitative filter paper range for general wet-chemistry workflows. The 55 mm size is convenient for micro- to small-scale filtrations, saving paper while maintaining consistent handling. Choose this grade when you need reliable qualitative performance with a faster filtration rate and a lighter paper structure suited to quicker separations.

Questions about Filter paper 604, qualitative ,fast, 79 g/sqm ,Discs 55 mm
What is this article?
Filter paper 604, qualitative ,fast, 79 g/sqm ,Discs 55 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.
