Description
Qualitative papers, grade 292, Ø 90 mm fluted filters are laboratory filter papers intended for analytical purposes that require a low ash content. The pre-pleated 90 mm format simplifies placement in funnels and supports efficient qualitative filtration in routine laboratory work. Each pack contains 100 pieces with a net weight of 0,081 kg, providing a practical supply for day-to-day analytical filtration. These fluted filters from manufacturer Sartorius are designed for qualitative analyses where low ash is important and gravimetric precision is not the primary requirement. The non-sterile papers originate from Germany and suit standard laboratory filtration setups. Grade 292 fluted discs help accelerate flow compared with flat sheets while maintaining the low-ash character needed for many qualitative procedures. They are appropriate for general analytical filtration, sample clarification and related bench applications that call for convenient pre-folded filter media in the 90 mm diameter range.

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.
