Description
Filter paper 400 is a medium-fast clarifying grade supplied as round filters with a basis weight of 61 g/m² and a diameter of 55 mm. It is intended for clarifying filtration in laboratory workflows that need a compact circular sheet and a balanced, medium-fast flow character. The 55 mm format suits small funnels and limited sample volumes while the 61 g/m² grammage provides a consistent paper matrix for routine clarifying steps. Each pack contains 100 pieces, offering a practical quantity for analytical and preparative clarifying work without excess bulk. Grade 400 from manufacturer Hahnemühle is specified for medium-fast clarifying performance in the round-filter format. Laboratories can use this paper where a defined diameter, grammage and filtration speed are required for standardised clarifying setups. The combination of medium-fast behaviour, 61 g/m² basis weight and 55 mm round geometry supports clear, repeatable clarifying filtration of laboratory suspensions and process aliquots in line with the stated product type.

What is this article?
Filter paper 400, for clarification ,medium fast, 61 g/sqm ,Discs 55 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.
