Description
Quantitative filter paper, 90 mm is a laboratory filtration medium for quantitative analytical work. It is specified at 84 g/m², described as fast-filtering, and marked with the white point grade indicator. The 90 mm circles fit common funnels and filtration assemblies used in routine gravimetric and sample-preparation steps. Packs contain 100 pc(s), giving a practical stock level for busy analytical benches. These discs from manufacturer filtraTECH supply a consistent quantitative paper grade for everyday laboratory filtration. The fast rating supports efficient processing of solutions where shorter filtration times are preferred, while the white point coding allows quick visual selection among graded papers. At 84 g/m² the sheet offers a workable balance for folding, seating in funnels, and handling during transfer. The 90 mm diameter aligns with standard laboratory glassware dimensions, simplifying setup across multiple workstations. Quantitative papers of this type are chosen when filtration behaviour and grade identity must remain clear and reproducible within established analytical protocols. This 90 mm format covers day-to-day quantitative filtration needs based on the stated basis weight, speed class, and white point marking.

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.
