Description
Quantitative filter paper, 185 mm is a circular laboratory filtration medium intended for analytical solid–liquid separations that benefit from a very slow flow rate. With a basis weight of 84 g/m² and the blue-dot speed marking, the sheets support controlled retention of fine precipitates during gravimetric work, sample clarification and routine preparation steps. The 185 mm diameter offers a practical working area for standard funnels and filtration assemblies used in chemistry, environmental and materials laboratories. Packaged as 100 pc(s), the discs are ready for day-to-day bench use where consistent handling and reproducible sheet properties are required. The very slow filtration characteristic helps build a stable filter cake and favours thorough particle capture without rushing the process. These quantitative papers from manufacturer filtraTECH fit established laboratory protocols for precipitate collection, wash steps and preparatory filtration ahead of further analysis. The combination of defined grammage, colour-coded speed class and convenient pack size makes the product a straightforward choice for structured analytical workflows that rely on dependable paper filtration.

Questions about Quantitative filter paper, 185 mm
What is this article?
Quantitative filter paper, 185 mm is the article on this page. Luminix Health distributes filtraTECH for laboratory use. It sits in Filter paper, inside Filtration, in Consommables.
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.
