Description
Qualitative filter papers Grade 293, 125 mm, are used for analytical purposes and general laboratory work when gravimetric analyses are not required. Thanks to their wet strength, they can be applied in pressure or vacuum filtration, remaining serviceable under suction or modest pressure during routine clarification and sample work-up. After use, the filter cake can be removed effortlessly with a water jet or spatula if required, aiding clean handling at the bench. Pack size is 100 pc(s), a convenient unit for standard funnel work and shared laboratory stocks. Net weight and gross weight are each 0,144 kg per pack. These qualitative papers from manufacturer Sartorius fit chemistry, life-science, and quality-control settings that need dependable particle separation without ash-free gravimetric determination. The 125 mm diameter matches common small-to-medium filtration setups, while Grade 293 targets everyday analytical filtration rather than quantitative residue analysis. Select this format for preparatory filtration, clarification, and general lab separations where wet strength, easy cake release, and a compact 125 mm sheet size support efficient daily workflows.

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.
