Description
Quantitative filter papers Grade 390 are laboratory filtration media intended for quantitative and gravimetric analyses as well as pressure or vacuum filtration. They are produced from 100% cotton linters with an alpha-cellulose content of greater than 98% and are acid-washed to obtain ash-free quality and high purity. This combination of raw material and washing supports clean blanks and reproducible results in analytical workflows. Offered in a pack of 100 pieces from manufacturer Sartorius, the papers suit routine sample preparation, residue determination and related gravimetric work in research and quality-control laboratories. The cotton-linter base provides a consistent cellulose matrix for filtration under pressure or vacuum, while the high alpha-cellulose level and acid treatment underpin the ash-free character required in quantitative methods. Net weight is 2,880 kg per pack, with origin in Germany. Grade 390 quantitative papers are a practical choice wherever ash-free, high-purity filter media are needed for gravimetric and quantitative filtration tasks without additional performance claims beyond the stated composition and use.

Questions about Quantitative Papers/ Grade 390
What is this article?
Quantitative Papers/ Grade 390 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.
