Description
Quantitative filter paper, 90 mm is a circular laboratory filter medium for quantitative analytical filtration. The paper has a basis weight of 84 g/m² and is specified as a very slow filtration grade, identified by the blue dot marking for this retention class. Each pack contains 100 pieces with a diameter of 90 mm, suited to larger funnels and filtration assemblies in chemical and analytical laboratories. This quantitative grade from manufacturer filtraTECH supports workflows that need controlled, slow filtration and clearly defined paper properties for precipitate collection and related laboratory procedures. The 84 g/m² substance together with the very slow flow characterises the sheet when retention is prioritised over throughput. Laboratories choose the 90 mm format for higher-volume setups, sample work-up and routine quantitative tasks within standard laboratory materials use. Consistent diameter and the blue-dot slow grade help keep filtration steps comparable across parallel samples. The product is supplied as ready-to-use circular sheets for everyday analytical filtration work.

Questions about Quantitative filter paper, 90 mm
What is this article?
Quantitative filter paper, 90 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.
