Description
Quantitative filter paper, 70 mm is a laboratory filtration medium designed for quantitative analytical work in mid-size funnel setups. The paper has a basis weight of 84 g/m² and is described as fast and hardened, combining relatively rapid flow with improved wet strength for washing, transfer, and multi-step sample handling. A 70 mm diameter bridges compact and larger funnel formats, making the circles suitable for routine environmental, food, and industrial laboratory filtrations at moderate sample volumes. Each pack contains 100 pc(s), supporting continuous use at shared filtration stations and in series analyses. This quantitative grade from manufacturer filtraTECH is intended for solid–liquid separation prior to drying, weighing, or further processing of retained solids. Hardened construction helps the disc remain intact under gravity or vacuum-assisted flow, while the fast character shortens filtration cycles when many samples are processed in parallel. Laboratories can incorporate these papers into established gravimetric and residue procedures that require consistent handling and clean filtrate collection. The format integrates readily with standard conical funnels and drying protocols used throughout quantitative wet-chemistry workflows.

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.
