Description
Qualitative filter paper Grade 293 with a 150 mm diameter is used for analytical purposes and general laboratory work when gravimetric analyses are not required. These qualitative filter papers offer wet strength that allows them to be used for pressure or vacuum filtration. After filtration, the filter cake can be removed effortlessly with a water jet or spatula whenever needed. Each pack contains 100 pieces in a 150 mm circle format that fits many standard laboratory funnels. Grade 293 papers from manufacturer Sartorius support routine separations, liquid clarification, and everyday sample preparation in research and quality-control environments. Their wet-strength construction helps the medium retain integrity during pressure or vacuum filtration. Consistent circle geometry supports reproducible setups on analytical benches across teaching, industrial, and academic laboratories. Straightforward cake release simplifies post-filtration handling and clean-up. This 150 mm Grade 293 qualitative paper is a practical consumable for day-to-day filtration tasks that require reliable wet performance and simple recovery of retained solids without gravimetric determination of the residue.

Questions about Qualitative Papers/ Grade 293
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 Consommables.
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.
