Description
Qualitative filter paper, folded, 150 mm is a ready-to-use laboratory filtration medium for routine qualitative separations. The paper is specified at 150 g/m² with medium/slow filtration behaviour, giving a practical balance between retention and throughput in standard funnel work. Pre-folded construction saves preparation time and supports consistent seating in conical funnels during sample clarification, precipitate collection and general wet-chemistry steps. At 150 mm diameter, the format fits common laboratory funnels used in teaching, quality control and research environments. Packs contain 100 pieces, offering a convenient working stock for daily filtration tasks. This folded qualitative filter paper from manufacturer filtraTECH follows the established 150 g/m² medium/slow profile for everyday qualitative grades. It is intended for applications where ash-free quantitative papers are not required, and where reliable handling and predictable medium/slow flow are the priority. The folded discs are straightforward to deploy straight from the pack into standard filtration set-ups.

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