Beschrijving
Quantitative filter paper, 47 mm, is a circular laboratory filter medium specified at 84 g/m² for quantitative analytical work. The grade is described as very fast filtration with a black point marking, supporting rapid separation of precipitates and particulates where short filtration times are advantageous. Diameter of 47 mm matches common small funnel and filtration assemblies used in routine wet-chemistry and sample preparation. Basis weight of 84 g/m² defines the paper substance for handling and flow behaviour during gravity or simple vacuum-assisted filtration. Supplied from manufacturer filtraTECH in packs of 100 pieces, the discs are suited to laboratories performing quantitative filtration steps that require consistent paper geometry and a fast-flowing grade. Use within standard laboratory filtration practice for collecting or clarifying samples where a quantitative paper type and very fast speed profile are specified. The compact 47 mm format supports efficient use in small-volume analytical procedures.

Questions about Quantitative filter paper, 47 mm
What is this article?
Quantitative filter paper, 47 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.
