Description
Filter paper 400 is a medium-fast grade intended for clarifying filtration in laboratory and technical workflows. It is supplied as folded filters with a diameter of 650 mm and a basis weight of 65 g/m², giving a practical format for removing particulates from liquids when a balanced flow rate is required. The pre-folded construction eases placement in funnels and supports efficient handling during routine clarifying steps. Grade 400 from manufacturer Hahnemühle is positioned for general clarifying duties rather than fine analytical separations. Each unit pack contains 100 folded filters, suitable for recurring sample preparation, process checks and teaching-laboratory use. The medium-fast filtration profile helps produce clearer filtrates while maintaining workable throughput compared with slower grades. The 650 mm diameter accommodates larger batch volumes and bulk clarification tasks. Defined basis weight supports consistent mechanical behaviour in standard aqueous filtration setups. These folded filters integrate into common laboratory funnels and technical filtration arrangements used for everyday clarifying work.

Questions about Filter paper 400, for clarification ,medium fast, 65 g/sqm ,Folded filter, 650 m
What is this article?
Filter paper 400, for clarification ,medium fast, 65 g/sqm ,Folded filter, 650 m 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.
