Description
Qualitative paper grade 292 a fluted filters, Ø 125 mm, are laboratory filter papers selected for analytical work that requires a low ash content. The fluted (pre-pleated) format is ready for use in funnels and supports efficient qualitative filtration during sample clarification and routine analytical preparation. Each pack contains 100 pieces, giving laboratories a practical working quantity for day-to-day bench procedures. With a net weight of 0,159 kg per pack, the 125 mm diameter suits common funnel sizes used in qualitative analysis. These grade 292 a papers from manufacturer Sartorius are intended for analytical purposes where minimising ash contribution from the filter medium is important. They are supplied non-sterile and are suited to general chemical and analytical laboratory workflows rather than sterile applications. Manufactured for consistent qualitative performance, the papers help maintain clean filtrates when ash-sensitive determinations or subsequent processing steps are planned. The product is stored at room temperature and integrates easily into standard filtration set-ups that call for reliable qualitative fluted filter media in the 125 mm size.
This article is part of Filter paper, in Filtration.

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.
