Beschrijving
Qualitative filter paper, folded, 70 mm is a pre-pleated laboratory filtration medium for routine qualitative separations and rapid sample clarification. It combines a basis weight of 88 g/m² with a fast filtration character, so liquids pass efficiently while particulates are retained for everyday analytical work. The 70 mm diameter matches common small funnels and is practical for teaching labs, QC benches, and research setups handling modest sample volumes. Delivered as a pack of 100 pieces from manufacturer filtraTECH, the folded format opens quickly in the funnel and reduces preparation time compared with flat discs. Typical uses include precipitate collection, washing steps, and polishing of aqueous or compatible organic mixtures before further examination. Qualitative-grade folded papers are selected when consistent throughput and easy handling matter most. The compact size keeps storage tidy and supports parallel filtrations at the bench. Choose this variant wherever a fast qualitative paper in a convenient pre-folded 70 mm circle is required.

Questions about Folded qualitative filter paper, 70 mm
What is this article?
Folded qualitative filter paper, 70 mm is the article on this page. Luminix Health distributes filtraTECH for laboratory use. It sits in Filter paper, inside Filtration, in Verbruiksartikelen.
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.
