Description
Filter paper 604 is a qualitative, fast-filtering folded filter paper with a basis weight of 79 g/m² and a diameter of 240 mm. Grade 604 is aimed at everyday laboratory separations where rapid flow and reliable clarification are required for qualitative applications. The pre-pleated folded format increases usable surface area and simplifies loading into larger funnels, supporting efficient processing of bulkier sample volumes, suspensions, and coarser precipitates. Supplied in packs of 100 pieces, the filters suit teaching laboratories, production QC, and research groups that run recurring qualitative filtration tasks. The 79 g/m² sheet weight balances open porosity for fast throughput with adequate mechanical stability for routine wet-chemistry handling. These Hahnemühle grade 604 folded filters match funnel geometries intended for 240 mm papers and work well for clarification and preparatory filtration before further analytical steps. Clear specification of grade, basis weight, and diameter helps standardise consumables across multi-user filtration stations.

Questions about Filter paper 604, qualitative ,fast, 79 g/sqm ,Folded filter, 240 mm
What is this article?
Filter paper 604, qualitative ,fast, 79 g/sqm ,Folded filter, 240 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.
