Description
Quantitative filter paper grade 393 is intended for quantitative and gravimetric analyses as well as for pressure or vacuum filtration. These filter papers are manufactured from 100% cotton linters with an alpha-cellulose content greater than 98% and are acid-washed to achieve ash-free character and high purity for demanding analytical applications. The pack comprises 100 pc(s) with a net weight of 2,622 kg and a gross weight of 3,000 kg, supporting efficient use across multiple filtration runs in the laboratory. Grade 393 quantitative papers from manufacturer Sartorius are selected when residue-conscious filtration and reliable recovery of precipitates are required in classical wet-chemistry and gravimetric procedures. Acid washing reduces inorganic ash contribution, which supports accurate weighing of retained solids after drying or ignition. The material is non-sterile and originates from Germany in the Lower Saxony region. Laboratories performing precipitate collection, sample clarification under vacuum or pressure, and general quantitative filtration specify cotton-linter cellulose papers of this type when matrix purity is critical. Grade 393 therefore provides a consistent cellulose medium for quantitative workflows that depend on low ash and high alpha-cellulose content.

Questions about Quantitative Papers/ Grade 393
What is this article?
Quantitative Papers/ Grade 393 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.
