Description
Qualitative papers Grade 131 as fluted filters with a diameter of 110 mm are intended for analytical laboratory work that requires a low ash content. These folded filter discs support routine qualitative separations, clarification steps and sample preparation where residual ash after ignition must stay minimal. The fluted geometry enlarges the effective filtration surface and promotes steady gravity flow in standard funnels. Pack size is 100 pieces, giving a practical stock unit for busy benches in chemistry, environmental analysis and quality control. Grade 131 papers from manufacturer Sartorius belong to a qualitative range developed for analytical purposes that demand controlled purity of the filter medium. With a net weight of 0,120 kg per pack they remain easy to handle and store under ordinary laboratory conditions. Non-sterile and suited to general wet-chemistry workflows, these 110 mm fluted filters help maintain consistent filtration performance without introducing high ash residues into subsequent determinations.

Questions about Qualitative Papers/ Grade 131
What is this article?
Qualitative Papers/ Grade 131 is the article on this page. Luminix Health distributes Sartorius 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.
