Description
Quantitative filter paper, 47 mm is a compact circular filtration medium for precise analytical work on a smaller scale. It features a basis weight of 84 g/m² and a very slow filtration rate, indicated by blue-dot coding on this grade. The 47 mm diameter suits small funnels, filter holders, and low-volume set-ups where fine particle retention and careful separation matter more than speed. Packs of 100 pieces support repeated use in analytical chemistry, environmental testing, and quality-control laboratories. This quantitative paper from manufacturer filtraTECH is aimed at gravimetric steps, precipitate collection, and sample preparation that benefit from a denser, very slow sheet. Very slow flow promotes thorough capture of fine solids and clearer filtrates when filtration time can be extended. Consistent diameter and basis weight aid reproducible handling across series of samples. Typical applications include micro-scale quantitative filtration, residue work, and clarification in research, industrial, and teaching laboratories that need a dependable very-slow quantitative grade in a practical pack size.

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 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.
