Description
Qualitative filter paper Grade 1290, 240 mm is designed for analytical filtration and general laboratory work where gravimetric analyses are not required. The large circular sheets support clarification, particle collection and routine sample handling in chemical, environmental and educational settings. Wet strength enables safe operation under pressure or vacuum, keeping the medium intact during assisted filtration. When filtration is finished, the filter cake can be detached readily with a water jet or spatula, facilitating recovery and straightforward cleanup of the disc. Supplied as 100 pieces per pack at 240 mm diameter and a net weight of 0,460 kg, the format fits larger funnels and higher-volume laboratory filtrations. Grade 1290 qualitative papers from manufacturer Sartorius are selected when quantitative ash-free performance is unnecessary yet reliable wet handling is still essential. Consistent sheet size promotes even seating in standard assemblies, while the robust construction supports gravity, pressure and vacuum protocols in day-to-day laboratory practice.

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.
