Description
Qualitative paper Grade 292 a fluted filters Ø 240 mm are laboratory filter papers intended for analytical purposes that require a low ash content. Each sales unit contains 100 fluted filters with a diameter of 240 mm, ready for use in standard filtration assemblies. The fluted design allows the papers to sit securely in funnels and provides a practical format for routine qualitative work. These Grade 292 a filters from manufacturer Sartorius support analytical procedures in which low ash contribution is relevant to subsequent sample evaluation. They suit clarification and particle retention steps in chemical analysis, quality-control laboratories and educational settings. The 240 mm diameter accommodates medium- to larger-volume filtrations commonly performed on the laboratory bench. Pack net weight is 0,495 kg, a quantity suited to regular laboratory consumption. Produced in Germany, the papers belong to the qualitative filter paper range used whenever a defined grade and low-ash orientation are specified. Integrating these fluted filters into daily workflows gives laboratories a consistent option for qualitative filtration that combines controlled ash behaviour with convenient handling.

Questions about Qualitative Papers/ Grade 292 a
What is this article?
Qualitative Papers/ Grade 292 a 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.
