Description
Filter paper 400 is a medium-fast folded filter paper designed for clarifying duties in laboratory and process environments. Supplied as pre-folded circles with a diameter of 200 mm, the format fits common funnels and supports efficient clarification of liquids. Grade 400 (Sorte 400) is specified with medium-fast filtration behaviour and a basis weight of 65 g/m², giving a practical balance between flow and retention of suspended solids. Each unit pack holds 100 pieces for continuous laboratory use. Manufactured by Hahnemühle, the pleated construction enlarges the effective surface area relative to a flat sheet of equal diameter and helps the filter sit stably during filtration. Applications range from sample preparation and solution clean-up to general wet-chemistry clarifying steps where medium-fast performance is preferred. Specify the 200 mm folded Filter paper 400 when a reliable clarifying grade in a convenient pre-pleated geometry is needed for routine 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.
