Description
Qualitative filter paper Grade 1290, 385 mm is used for analytical purposes and general laboratory filtration where gravimetric analyses are not required. Wet strength allows the sheets to be applied in pressure or vacuum filtration while retaining mechanical stability throughout the process. After the run, the filter cake can be detached effortlessly with a water jet or spatula, easing solids recovery and reducing handling time at the bench. Packs of 100 pieces at 385 mm diameter provide a large working area for higher-volume samples and broader funnels or filtration assemblies. Grade 1290 papers from manufacturer Sartorius support everyday clarification, precipitate collection, and related non-quantitative tasks in research, teaching, and quality-control laboratories. Their wet-strength design helps preserve filter integrity when gravity filtration is supplemented by pressure or vacuum assistance. Select this large-diameter format when qualitative separation capacity and convenient cake removal matter more than ashless quantitative specifications.

Questions about Qualitative Papers/ Grade 1290
What is this article?
Qualitative Papers/ Grade 1290 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.
