Description
Qualitative filter paper Grade 293, 460 x 570 mm, serves analytical purposes and general laboratory work when gravimetric analyses are not required. Owing to its wet strength, the paper can be used for pressure or vacuum filtration, and the filter cake can be removed effortlessly with a water jet or spatula when needed. Packs provide 100 sheets in the 460 x 570 mm format, with a net weight of 2,100 kg and a gross weight of 2,280 kg. These qualitative papers from manufacturer Sartorius support everyday filtration in research, teaching, and quality-control laboratories that require dependable sheet media without gravimetric demands. Wet strength helps maintain sheet integrity during pressure-assisted or vacuum-driven steps, while cake release remains simple for further processing. Grade 293 in this larger sheet size suits bigger funnels, trays, or preparatory layouts on the bench. Produced in Germany and supplied non-sterile, the sheets fit standard laboratory handling for qualitative separations, clarification, and general sample work where quantitative gravimetric analysis is not specified.

What is this article?
Qualitative Papers/ Grade 293 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.
