Description
Qualitative filter paper Grade 1291, 600 mm is a laboratory filtration medium intended for analytical purposes and general laboratory work whenever gravimetric analyses are not required. The 600 mm sheets offer a practical large-format option for routine separations and sample preparation in everyday laboratory procedures. Thanks to their wet strength, these papers can be used for pressure or vacuum filtration while remaining workable under wet conditions. After filtration, the filter cake can be removed effortlessly with a water jet or spatula, supporting clean handling and efficient workflow. Supplied in packs of 100 pieces, the 600 mm diameter suits large funnels and filtration setups found in research and quality-control 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.
