Description
Filter paper 400 is a medium-fast folded filter paper for clarifying applications in laboratory and technical settings. The pre-pleated circles measure 250 mm in diameter and provide a ready-to-use format for funnel-based clarification of larger liquid volumes. Grade 400 (Sorte 400) features medium-fast filtration behaviour and a basis weight of 80 g/m², supporting effective reduction of suspended matter with practical throughput. Packs of 100 pieces cover regular laboratory demand without frequent reordering. This folded filter paper from manufacturer Hahnemühle offers increased effective filtration area versus a flat disc of the same diameter and seats securely in standard funnels. Typical contexts include sample preparation, solution clean-up and general wet-chemistry clarification where a medium-fast grade 400 paper is specified. Choose the 250 mm folded Filter paper 400 when consistent clarifying performance and a larger pleated geometry are required for day-to-day filtration work.

What is this article?
Filter paper 400, for clarification ,medium fast, 65 g/sqm ,Folded filter, 250 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.
