Description
Quantitative filter papers Grade 392 are laboratory filter papers intended for quantitative and gravimetric analyses as well as for pressure or vacuum filtration. They are manufactured from 100% cotton linters with an alpha-cellulose content of greater than 98% and are acid-washed to achieve ash-free quality and high purity for analytical work. Grade 392 papers from manufacturer Sartorius support precipitate recovery, residue determination and clarification steps in chemical, environmental and quality-control laboratories. Each unit is supplied as a pack of 100 pieces, suited to routine series and method work that relies on consistent filtration media. The cotton-linter base together with acid washing underpins the ash-free character required when filters are dried and weighed after use. These papers can be applied in standard gravity setups or under pressure- or vacuum-assisted conditions, offering flexibility across common laboratory filtration assemblies. They provide a practical medium wherever high-purity quantitative paper is needed ahead of gravimetric evaluation. Pack net weight is 0,137 kg.
This article belongs on Filter paper, in Filtration.

Questions about Quantitative Papers/ Grade 392
What is this article?
Quantitative Papers/ Grade 392 is the article on this page. Luminix Health distributes Sartorius 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.
