Description
Qualitative papers Grade 292 are fluted filter papers for analytical laboratory use where a low ash content is required. At 240 mm diameter, this size addresses larger funnels and bulkier sample volumes in qualitative filtration, clarification, and solid–liquid separation tasks. The grade is selected when residual ash from the paper must stay low so that subsequent analytical steps are not compromised by the filter medium. Packs of 100 pc(s) with a net weight of 0,464 kg support consistent replenishment in high-throughput or multi-user laboratories. These Grade 292 fluted filters from manufacturer Sartorius are non-sterile products intended for ordinary bench handling and room-temperature storage. Pre-pleating enlarges the effective filtration area compared with flat discs of the same diameter, which can assist flow when processing bigger batches. The 240 mm variant is appropriate whenever protocols name Grade 292 qualitative paper at this diameter for research, teaching, or quality-control filtrations that depend on low-ash performance in a larger format.

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.
