Description
Quantitative ash-free filter paper is a fast-filtering round filter for analytical laboratory use. Produced exclusively from pure cotton cellulose fibres, this ash-free paper contains a maximum of 0,002 % ash and supports clean quantitative work with minimal residue. A grammage of 80 g/m², pore size of 10–15 µm and thickness of 250 µm combine rapid flow with retention of bulky precipitates such as iron hydroxide and numerous metallic sulphides. The 125 mm diameter discs are supplied as a pack of 100 pieces and are offered as circular filters equivalent to Whatman 43. This cellulose filter medium from manufacturer Labbox suits routine and specialised filtration steps where speed and low ash content matter. It integrates readily into precipitate collection, sample clarification and gravimetric preparation workflows in research, teaching and quality-control laboratories that require consistent, ash-free quantitative filter paper in a convenient 125 mm format.

Questions about Ashless quantitative filter paper, high flow rate, 125 mm, 100 pcs
What is this article?
Ashless quantitative filter paper, high flow rate, 125 mm, 100 pcs is the article on this page. Luminix Health distributes Labbox 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.
