Description
Filter paper 400 is a medium-fast clarifying grade supplied as round filters with a diameter of 500 mm and a basis weight of 61 g/m². Grade 400 is intended for clarifying work in the laboratory, where moderate filtration speed supports efficient removal of coarser particles and turbidity from liquids. The 500 mm format suits larger funnels and higher-volume sample handling, while the 61 g/m² sheet weight offers a practical balance of handling stability and flow for routine clarifying steps. Packs contain 100 pieces, convenient for continuous bench or preparative use. These round filters are offered by manufacturer Hahnemühle as product type grade 400 within the qualitative filter-paper range. The material is non-sterile and suited to standard technical and analytical clarification workflows rather than sterile processing. Origin is France. With a pack gross weight of 1,70 kg, the unit is straightforward to store and dispense in shared laboratory stock. Choose this grade when medium-fast clarifying performance and a large round diameter are required for everyday filtration tasks.

What is this article?

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.
