Description
Qualitative filter paper, folded, 320 mm is a laboratory-grade cellulose filter medium supplied as pre-folded circles for routine qualitative separations. With a basis weight of 80 g/m² and a slow filtration rating, the paper supports controlled gravity filtration of precipitates and suspensions where retention and clarity matter more than high throughput. The 320 mm diameter suits larger funnels and batch work, while the folded format reduces preparation time and helps the sheet seat evenly in the funnel cone. Each pack contains 100 pc(s), giving laboratories a practical stock quantity for teaching labs, quality control, and general analytical workflows. This qualitative grade from manufacturer filtraTECH is intended for applications that do not require quantitative ash-free papers, focusing instead on reliable particle retention and straightforward handling. The combination of moderate grammage, slow flow, and generous diameter makes the circles suitable for clarifying solutions, collecting coarse to medium precipitates, and everyday sample preparation steps in chemical and life-science laboratories.

Questions about Folded qualitative filter paper, 320 mm
What is this article?
Folded qualitative filter paper, 320 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.
