Description
Filter paper 604 is a qualitative folded filter made for fast filtration in laboratory practice. It offers a basis weight of 79 g/m² and a diameter of 125 mm, providing a defined grade when rapid throughput is preferred over the slowest retention grades. Pre-folded discs drop into standard funnels and save the time otherwise spent creasing flat sheets. Grade 604 from manufacturer Hahnemühle is specified for qualitative analytical work rather than quantitative ash-free determinations. Supplied in packs of 100 pieces, the filters support routine sample clarification, coarse precipitate collection, and general wet-chemistry procedures that benefit from a faster filtration rate. Stable paper construction and the folded form help keep handling consistent across the pack. These filters suit teaching, research, and quality-control laboratories that require qualitative fast filter paper of grade 604 at 125 mm diameter and 79 g/m² basis weight for everyday filtration steps.

Questions about Filter paper 604, qualitative ,fast, 79 g/sqm ,Folded filter, 125 mm
What is this article?
Filter paper 604, qualitative ,fast, 79 g/sqm ,Folded filter, 125 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.
