Description
Quantitative filter paper, 90 mm is a pre-cut circular filtration medium for quantitative laboratory applications. Featuring a grammage of 84 g/m² and a very fast filtration rating marked by a black dot, it is designed for efficient separation of solids from liquids during gravimetric analysis, precipitate recovery and general sample clarification. The 90 mm diameter matches larger funnels and filtration hardware typically found in analytical, industrial QC and research laboratories that process higher sample volumes. Each pack contains 100 pc(s), providing a practical stock of ready-to-use discs for routine wet-chemistry workflows. This quantitative grade from manufacturer filtraTECH pairs defined basis weight with very fast flow behaviour, supporting rapid throughput while retaining the handling simplicity of standard circular filter paper. It is suited to laboratory procedures that specify quantitative filter paper in the 90 mm size class and can be applied directly in established filtration protocols without additional cutting or conditioning steps.
This article is part of Filter paper, in Filtration.

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