Description
Quantitative filter paper, 240 mm is a laboratory-grade circular filter medium intended for quantitative analytical work where controlled particle retention and consistent flow behaviour are required. With a basis weight of 84 g/m² and a medium filtration speed indicated by the red-dot coding, it supports routine gravimetric and wet-chemistry separations in research, quality control, and teaching laboratories. The 240 mm diameter suits larger funnels and Büchner setups, giving ample surface area for sample loads while maintaining even wetting and cake formation. Supplied in packs of 100 pieces from manufacturer filtraTECH, the sheets are ready for standard ash-related quantitative procedures and general solid–liquid separations. Medium-speed performance balances throughput with clarity of filtrate, making the paper a practical choice for precipitates of intermediate particle size. Use it for sample preparation, residue collection, and everyday filtration steps that demand reproducible paper characteristics without unnecessary complexity. Clear diameter marking and the established red-dot speed class help laboratories standardise consumables across benches and instruments.

Questions about Quantitative filter paper, 240 mm
What is this article?
Quantitative filter paper, 240 mm is the article on this page. Luminix Health distributes filtraTECH 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.
