Description
Qualitative folded filter paper, 125 mm is a laboratory filtration medium intended for everyday qualitative separations. With a basis weight of 80 g/m² and very slow filtration behaviour, it supports thorough retention of fine precipitates under gravity flow. The 125 mm diameter matches widely used funnels in analytical, teaching, and quality-control laboratories. Each pack contains 100 pieces in a pre-folded format, so the papers can be placed directly into the funnel and help keep sample preparation efficient. This filter paper from manufacturer filtraTECH is suited to qualitative work where controlled throughput and dependable particle capture are required rather than quantitative ash-free grades. Common uses include solution clarification, precipitate collection, and general wet-chemistry steps in research and educational settings. The moderate sheet weight together with the slow speed and mid-size diameter aids consistent handling of fine or gelatinous solids. Choose this 125 mm folded paper when a ready-to-use qualitative medium is needed for routine laboratory filtration.

Questions about Folded qualitative filter paper, 125 mm
What is this article?
Folded qualitative filter paper, 125 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.
