Description
Quantitative filter paper, 70 mm is a circular laboratory filtration medium intended for quantitative analytical work. It has a basis weight of 84 g/m² and is specified as a fast, white-dot grade, supporting efficient solid–liquid separation where throughput and consistent handling are important. The 70 mm diameter fits common mid-size funnels and filter holders used in gravimetric analysis, sample clean-up, and routine quality-control steps. Packaged as 100 pc(s), the discs provide a convenient stock format for daily bench use. Available from manufacturer filtraTECH, this quantitative paper is suited to procedures in which filtrate or retained solids must be processed under controlled laboratory conditions. The relatively light 84 g/m² sheet weight aids flow during filtration of precipitates, environmental aliquots, or process samples, while the fast white-dot rating indicates a grade oriented toward rapid filtration rather than the slowest fine-retention papers. Laboratories can integrate the 70 mm circles into established protocols without changing standard apparatus dimensions, making them a practical consumable for chemistry, materials, and general analytical workflows that rely on reproducible quantitative filter paper.

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 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.
