Description
Filter paper 400 is a medium-fast clarifying grade offered as round filters measuring 150 mm in diameter with a basis weight of 61 g/m². Intended for laboratory clarification of liquids, this grade 400 paper provides a practical balance between filtrate clarity and filtration speed for routine sample work. The larger circular format suits standard funnels and filtration set-ups used in analytical chemistry, quality control, and general wet-lab practice. Packs of 100 pieces support continuous use in clarifying steps, solvent recovery, and everyday preparation of solutions before further analysis. Manufactured by Hahnemühle, the paper delivers consistent grammage and medium-fast flow characteristics that help laboratories keep clarifying procedures reproducible from batch to batch. It is well suited where a dependable qualitative filter paper is needed for pre-filtration or simple particulate removal. With its 150 mm diameter and defined 61 g/m² sheet weight, this round filter is a clear option for medium-scale clarifying tasks in research and industrial laboratory environments.

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.
