Description
Filter paper 400 is a medium-fast round filter intended for clarifying work in the laboratory. Grade 400 combines a basis weight of 61 g/m² with a 70 mm diameter, giving a practical format for routine separation of particulates from liquids where balanced retention and flow are required. The circular sheets fit standard funnels and filtration assemblies used in analytical and preparative workflows. Packaged as 100 pieces, the filters support repeated clarifying steps, sample clean-up, and general laboratory filtration without changing paper grade between runs. Medium-fast filtration behaviour suits suspensions and process streams that need efficient throughput while still delivering clear filtrates. This grade 400 paper from manufacturer Hahnemühle offers consistent basis weight for reproducible handling on the bench. The 70 mm round format is well matched to smaller funnels and compact filtration setups. Laboratories can rely on these clarifying filters for everyday sample preparation, qualitative work, and related applications that call for medium-fast paper performance in a convenient round geometry.

What is this article?
Filter paper 400, for clarification ,medium fast, 61 g/sqm ,Discs 70 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.
