Description
Qualitative filter paper, 240 mm, is a large-format circular filtration medium for qualitative laboratory separations and bulk sample clarification. It combines a basis weight of 150 g/m² with a medium/slow filtration rate, delivering steady retention and controlled flow for routine wet-chemistry tasks. Applications include precipitate collection, suspension clarifying, and general sample work-up where ash-free quantitative grades are unnecessary. Packs contain 100 pc(s), giving ample stock for high-throughput benches, teaching laboratories, and quality-control environments. The 240 mm diameter suits larger funnels and higher liquid volumes while still folding cleanly for gravity filtration cones. Medium/slow porosity is appropriate for moderately fine particles, limiting premature clogging without sacrificing workable throughput. This qualitative paper from manufacturer filtraTECH supports everyday filtration in chemical, biological, and process-check settings. Consistent sheet mass and defined filtration characteristics aid reproducible day-to-day handling. Use this grade when a spacious 240 mm working diameter, dependable qualitative performance, and convenient multi-piece packaging are priorities for preparative and analytical laboratory filtration.

Questions about Qualitative filter paper, 240 mm
What is this article?
Qualitative 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 Consommables.
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.
