Description
Filter paper 400 is a medium-fast clarifying grade offered as a round filter with a 240 mm diameter and a basis weight of 61 g/m². It supports laboratory clarification tasks that need moderate filtration speed together with dependable particle retention during routine sample preparation. The larger circular format suits funnels and holders sized for 240 mm discs and is practical for higher-volume clarifying steps in analytical and process laboratories. Supplied in a pack of 100 pieces, it covers multi-run sequences and steady laboratory consumption. Grade 400 from manufacturer Hahnemühle is designated for clarifying use, assisting removal of suspended matter to improve liquid clarity before further work. Medium-fast performance balances flow with capture for everyday laboratory liquids. The 240 mm round geometry eases seating, folding where required, and disposal after use. Uniform basis weight aids consistent handling across the pack. This filter paper fits established wet-lab protocols in quality control, research, and teaching environments where clarifying filtration is a standard preparatory operation.

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.
