Description
Qualitative papers Grade 292 are fluted filter papers designed for analytical applications that call for a low ash content. The 185 mm diameter suits larger funnels and higher-volume qualitative filtrations in chemical, environmental, and general laboratory practice. These papers are used where solids must be retained and the filter contribution to ash remains low, supporting clean results in routine analytical workflows. Supplied in packs of 100 pc(s) with a net weight of 0,276 kg, they are convenient for laboratories that process many samples of this size. Grade 292 fluted filters from manufacturer Sartorius arrive non-sterile and are intended for standard room-temperature storage and handling. The fluted construction presents a greater working surface than a flat sheet of equal diameter, which can improve throughput during clarification or precipitate collection. Choose the 185 mm option when methods specify Grade 292 qualitative paper at this diameter for preparatory filtration, teaching demonstrations, or day-to-day quality-control separations that depend on low-ash filter media.
This article is part of Filter paper, in Filtration.

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