Description
Qualitative paper grade 292 a fluted filters, Ø 185 mm, are laboratory filter papers designed for analytical purposes that require a low ash content. The fluted, pre-pleated form is ready for funnel use and supports efficient qualitative filtration during clarification and sample preparation. Each unit pack holds 100 pieces, offering a practical supply for regular laboratory demand. Net weight is 0,309 kg per pack, and the 185 mm diameter addresses larger funnel sizes common in qualitative analysis. These grade 292 a papers from manufacturer Sartorius serve workflows in which ash contribution from the filter medium must remain low. They are non-sterile products intended for general chemical and analytical laboratory filtration, not for sterile applications. Consistent qualitative paper performance supports clean filtrates when subsequent analytical or processing steps are ash-sensitive. Stored at room temperature, the 185 mm fluted filters fit standard bench filtration set-ups that need reliable qualitative media in this larger diameter.
This article is part of Filter paper, in Filtration.

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