Description
Filter paper 400 is a medium-fast round filter designed for clarifying applications in laboratory practice. With a basis weight of 61 g/m² and a diameter of 90 mm, grade 400 provides a versatile format for separating solids from liquids when moderate filtration speed is preferred. The round sheets seat readily in common funnels and support analytical, preparative, and routine sample-preparation tasks. Supplied in packs of 100 pieces, the paper enables consistent clarifying steps across multiple samples without switching grades. Medium-fast flow characteristics help achieve clear filtrates from suspensions and similar matrices while maintaining practical throughput. Produced by Hahnemühle, this grade 400 filter paper offers uniform basis weight for dependable handling during everyday filtration. The 90 mm diameter suits mid-size funnels and standard bench filtration assemblies. Laboratories use these round filters for clarifying work, general liquid clean-up, and related procedures that benefit from medium-fast paper performance in a widely used circular size.

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.
