Description
Qualitative papers Grade 292 are fluted filter papers intended for analytical laboratory work that requires a low ash content. With a diameter of 150 mm, this format fits common funnels and filtration assemblies used in qualitative analysis, sample clarification, and routine solid–liquid separation. The papers support procedures where residual ash must remain low enough for reliable analytical follow-up, without introducing unnecessary background from the filter medium itself. Each pack contains 100 pc(s) and has a net weight of 0,222 kg, making stock planning straightforward for busy laboratories. These Grade 292 fluted filters from manufacturer Sartorius are supplied non-sterile for conventional bench workflows. The pre-pleated geometry increases the effective filtration surface relative to a flat disc of the same diameter, which can aid flow during everyday filtrations. Suitable for research, teaching, and quality-control environments that specify qualitative filter paper with low ash demand, the 150 mm variant is a practical choice whenever protocols call for this grade and size in standard analytical setups.

Questions about Qualitative Papers/ Grade 292
What is this article?
Qualitative Papers/ Grade 292 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.
