Description
Qualitative filter paper, folded, 90 mm is a pre-pleated laboratory filtration medium intended for routine qualitative separations and general sample clarification. Featuring a basis weight of 88 g/m² and fast filtration behaviour, it promotes efficient liquid flow while retaining particulates in day-to-day analytical practice. The 90 mm diameter fits widely used funnels and suits moderate sample volumes in research, teaching, and quality-control environments. Supplied in packs of 100 pieces from manufacturer filtraTECH, the folded construction seats quickly in the funnel and shortens set-up compared with flat sheets. Typical applications cover precipitate collection, washing operations, and polishing of process liquids ahead of further examination. Qualitative-grade folded papers are valued when dependable throughput and simple handling are essential. The 90 mm size balances filtration area with convenient storage and supports parallel work at the bench. Select this format for standard aqueous filtrations and compatible solvent systems that need a fast qualitative paper in a ready-to-use folded circle.

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