Description
Quantitative filter paper, 70 mm is a laboratory filtration medium intended for quantitative analytical applications. It has a basis weight of 84 g/m² and is specified as medium speed and hardened, combining workable flow with improved mechanical stability when wet. Discs of 70 mm diameter suit standard funnels and filtration set-ups used for gravimetric work, precipitate washing and routine sample preparation in analytical and quality-control laboratories. The hardened character supports handling during rinsing and transfer and helps reduce tearing under wet conditions, while medium filtration behaviour balances retention of solids with practical filtration times. Packs of 100 pieces from manufacturer filtraTECH support steady laboratory throughput and parallel determinations that depend on a consistent paper matrix. The defined basis weight contributes to reproducible performance across batches and methods. These papers are suitable for research, education and industrial QC environments that need dependable quantitative filter paper in a 70 mm format for everyday solid–liquid separations and wet-chemistry workflows.
This article is part of Filter paper, in Filtration.

Questions about Quantitative filter paper, 70 mm
What is this article?
Quantitative 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 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.
