Description
Quantitative filter paper, 90 mm is a laboratory filtration medium for analytical and preparative work that requires controlled, slow flow. It has a basis weight of 75 g/m² and is marked as slow filtration (green point), supporting careful retention of fine precipitates during quantitative procedures. The 90 mm circular format fits common funnels and filtration holders used in chemical, environmental and teaching laboratories. Packs contain 100 pieces and are offered by manufacturer filtraTECH for routine bench use. Typical applications include gravimetric analysis, collection of precipitates, clarification of sample solutions and stepwise sample preparation where a measured filtrate rate is preferred to rapid throughput. The quantitative grade is intended for workflows that need consistent sheet behaviour without adding unnecessary variables to the analytical sequence. Slow green-point papers are often chosen when fine solids must be held on the paper and when unhurried collection of the filtrate supports accurate weighing or further wet-chemistry steps. The 75 g/m² weight gives practical handling strength for everyday laboratory filtration tasks.

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.
