Description
Qualitative filter paper Grade 293, 270 mm is a laboratory filtration medium intended for analytical purposes and general laboratory work when gravimetric analyses are not required. Thanks to its wet strength, the paper can be used for pressure or vacuum filtration. When needed, the filter cake can be removed effortlessly from the filter using a water jet or spatula. Available as a single piece with a net weight of 0,458 kg, this 270 mm diameter format suits common laboratory funnels and filtration assemblies used in analytical and preparative settings. These qualitative papers from manufacturer Sartorius support routine clarification and separation tasks across research and everyday laboratory environments. Grade 293 is selected wherever dependable qualitative filtration is required and quantitative gravimetric work is not part of the method. Wet strength enables reliable handling during pressure- or vacuum-assisted steps, and the filter cake can be detached cleanly so that subsequent processing remains straightforward. Laboratories performing general analytical filtrations will find this 270 mm Grade 293 paper a practical choice for consistent day-to-day use.

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 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.
