Description
Qualitative filter paper, 150 mm, is a circular laboratory filtration medium intended for routine qualitative separations and sample clarification. It has a basis weight of 150 g/m² and a medium/slow filtration characteristic, giving a practical balance between retention and flow for everyday wet-chemistry work. These sheets are used to collect precipitates, clarify suspensions, and prepare samples where quantitative ash determination is not required. Pack size is 100 pc(s), supporting continuous bench use in teaching, research, and quality-control laboratories. The 150 mm diameter fits common funnels and holders and folds readily into cones for gravity filtration. Medium/slow porosity helps manage moderately fine particles without excessive clogging or uncontrolled throughput. This grade from manufacturer filtraTECH is positioned for general laboratory filtration tasks in chemistry, biology, and process-check environments. Consistent sheet weight and defined filtration behaviour support reproducible handling across batches of routine analyses. Choose this qualitative paper when reliable day-to-day filtration performance, convenient pack sizing, and a standard 150 mm working diameter are needed for preparative and analytical workflows.

Questions about Qualitative filter paper, 150 mm
What is this article?
Qualitative filter paper, 150 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.
