Description
Qualitative papers, grade 1288, 90 mm are qualitative filter papers for analytical purposes and general laboratory work when gravimetric analyses are not required. Their wet strength allows use under pressure or vacuum filtration, and the filter cake can be removed easily with a water jet or spatula when needed. Supplied in packs of 100 pieces at 90 mm diameter with a net weight of 0,080 kg, these discs support everyday qualitative filtration tasks. Grade 1288 from manufacturer Sartorius is intended for routine analytical filtration and general lab applications rather than ash-critical gravimetry. The non-sterile papers originate from Germany and fit standard funnel and filtration assemblies. Wet-strength qualitative media of this type are useful for clarifying samples, collecting precipitates that must later be recovered, and performing pressure- or vacuum-assisted steps on the bench. Laboratories can rely on the 90 mm format for consistent handling across common filtration glassware and apparatus without additional performance claims beyond the stated qualitative and wet-strength characteristics.

Questions about Qualitative Papers/ Grade 1288
What is this article?
Qualitative Papers/ Grade 1288 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.
