Description
Filter funnel 4000 ml, Por. 2 is a large-capacity laboratory filtration funnel manufactured from borosilicate glass 3.3. It incorporates a VitraPOR® sintered filter plate of 180 mm diameter with porosity grade 2 and a working height of 206 mm above the filter plate. This design supports efficient vacuum filtration of substantial liquid volumes in chemical synthesis, sample preparation and analytical workflows. The porosity 2 frit is suited to medium-retention separations commonly required in preparative chemistry and quality-control laboratories. Supplied as a single unit from manufacturer ROBU - Stereon, the funnel combines chemical resistance with thermal stability typical of borosilicate 3.3 glassware. Its generous 4000 ml capacity and wide filter area facilitate rapid processing of suspensions while maintaining clear filtrate collection. The robust construction is intended for repeated use under standard laboratory vacuum conditions, making it a practical choice for routine and scale-up filtration tasks where reliable glass frit performance is essential.

Questions about Filter Funnel, 4000 ml, Por. 2
What is this article?
Filter Funnel, 4000 ml, Por. 2 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.
