Description
Qualitative filter paper Grade 1291, 580 x 580 mm is used for analytical purposes and general laboratory work when gravimetric analyses are not required. These qualitative filtration sheets provide a practical medium for routine solid–liquid separations and everyday laboratory filtration tasks. Through their wet strength they can be employed for pressure or vacuum filtration, offering flexible handling beyond simple gravity set-ups. After use, the filter cake can be removed effortlessly with a water jet or spatula, simplifying recovery of retained solids and clearing of the filter surface. Grade 1291 sheets measuring 580 x 580 mm from manufacturer Sartorius are supplied in packs of 100 pc(s), a convenient quantity for analytical benches and shared laboratory facilities. The large sheet format suits correspondingly sized funnels and filtration assemblies while supporting consistent preparation from run to run. Laboratories select this qualitative grade whenever reliable separation performance and straightforward cake release matter more than gravimetric determination, helping standardise general filtration workflows across research and routine testing environments.

Questions about Qualitative Papers/ Grade 1291
What is this article?
Qualitative Papers/ Grade 1291 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.
