Description
Qualitative filter paper, 90 mm is a standard circular filter medium for everyday qualitative laboratory filtration. At 80 g/m² and rated very slow, the paper is suited to gravity filtration tasks that benefit from higher retention and clearer filtrates rather than maximum speed. The 90 mm diameter fits widely used funnels and supports typical bench-scale separations of precipitates and particulate suspensions. Each unit pack holds 100 pc(s), offering a practical quantity for teaching laboratories, quality-control benches, and general analytical preparation. This qualitative paper from manufacturer filtraTECH is intended for workflows that do not demand quantitative ash-free grades, emphasising reliable handling and consistent particle capture instead. Very slow filtration behaviour helps when fine solids must be retained and solutions clarified under ambient gravity conditions, making the 90 mm circles a versatile choice for routine chemical, environmental, and life-science sample work.

Questions about Qualitative filter paper, 90 mm
What is this article?
Qualitative filter paper, 90 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.
