Description
Filter funnel, conical, 170 ml, Por. 3 is a precision laboratory funnel manufactured from borosilicate glass 3.3. The conical body has an outer diameter of 100 mm and incorporates a permanently fused VitraPOR® filter plate of 35 mm diameter with porosity grade 3. With a working capacity of 170 ml, the funnel is intended for vacuum or gravity filtration of analytical samples, precipitates and suspensions in chemical, pharmaceutical and environmental laboratories. The chemically resistant borosilicate construction withstands thermal shock and aggressive solvents while the defined porosity ensures reproducible particle retention. Offered as a single unit from manufacturer ROBU - Stereon, this conical filter funnel provides a reliable, reusable solution for routine solid–liquid separations where controlled filtration performance is required. The integrated sintered-glass disc eliminates the need for separate filter papers in many applications and maintains dimensional stability under laboratory conditions.
This article belongs on Sintered glass filter plates & discs, in Filtration.

Questions about Filter Funnel, Conical, 170 ml, Por. 3
What is this article?
Filter Funnel, Conical, 170 ml, Por. 3 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.
