Description
Filter funnel 8000 ml porosity 4 is a large-capacity laboratory filtration vessel manufactured from borosilicate glass 3.3. It incorporates a VitraPOR® filter disc of 205 mm diameter with porosity grade 4 and provides a working height of 280 mm above the filter plate. The robust borosilicate construction delivers the chemical resistance and thermal stability required for demanding filtration tasks in research and production laboratories. The generous 8000 ml volume accommodates substantial sample quantities, while the porosity-4 frit ensures controlled particle retention. This design supports efficient vacuum or gravity filtration of suspensions, precipitates and culture media. The unit from manufacturer ROBU - Stereon is supplied as a single piece and integrates readily into existing filtration setups. Its combination of large diameter filter plate and tall cylindrical section above the frit promotes high throughput and clear visual monitoring of the filtration process, making it a practical choice for preparative work, sample clarification and bulk solid–liquid separations in the laboratory.

Questions about Filter Funnel, 8000 ml, Por. 4
What is this article?
Filter Funnel, 8000 ml, Por. 4 is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
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.
