Description
Qualitative filter paper, 90 mm is a laboratory filtration medium for routine qualitative separations and general sample clarification. It offers a basis weight of 88 g/m² together with a fast filtration rate, enabling efficient flow when rapid processing is preferred to quantitative ash-free analysis. Supplied as circular sheets of 90 mm diameter in packs of 100 pc(s), the papers suit standard funnels and filtration hardware common in research, teaching, and quality-control laboratories. The qualitative grade from filtraTECH is designed for everyday analytical work including precipitate collection, solution polishing, and preparatory filtration steps that benefit from consistent handling and dependable particle retention. Stated properties are limited to weight, speed, diameter, and pack format, keeping specification clear for chemistry and life-science protocols that rely on reproducible qualitative filtration media. These 90 mm discs integrate easily into existing bench routines that require fast qualitative filter paper in a practical laboratory pack size.

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 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.
