Description
Filter paper 400 is a medium-fast clarifying grade supplied as round filters with a diameter of 125 mm and a basis weight of 61 g/m². Designed for routine laboratory clarification work, this grade 400 paper supports efficient removal of particulates from liquids while maintaining a practical filtration rate suited to everyday sample preparation. The circular format fits standard funnels and filtration assemblies used in analytical, quality-control, and teaching laboratories. Each pack contains 100 pieces, giving a convenient stock quantity for repeated clarifying steps, solvent work-ups, and general wet-chemistry workflows. Produced by Hahnemühle, the paper combines a defined grammage with medium-fast flow behaviour that balances clarity of the filtrate against throughput. Its consistent sheet properties help laboratories standardise clarifying procedures across batches and operators. Suitable where a reliable qualitative filter paper is required for pre-filtration or simple clarification prior to further analysis or processing, this 125 mm round filter is a straightforward choice for general laboratory filtration tasks.

What is this article?
Filter paper 400, for clarification ,medium fast, 61 g/sqm ,Discs 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.
