Description
Conical filter funnel 25 ml, Por. 5 is a laboratory glassware item manufactured from borosilicate 3.3 glass. The conical body has a diameter of 55 mm and is fitted with an integrated VitraPOR® filter plate of 25 mm diameter at porosity grade 5, enabling controlled filtration without separate media. This design supports analytical sample preparation, residue collection and routine liquid clarification in chemistry and quality-control laboratories. Chemical resistance and thermal stability of the borosilicate construction allow use with a wide range of aqueous and organic solvents. Supplied in packs of 10 pieces from manufacturer ROBU - Stereon, the funnel integrates readily into standard filtration assemblies and stands. The sintered VitraPOR® plate provides consistent pore performance for reproducible results across multiple runs. Its compact conical geometry facilitates efficient drainage and easy cleaning between samples, making it a practical choice for both teaching and research environments where reliable porosity-grade filtration is required.

Questions about Filter Funnel, Conical, 25 ml, Por. 5
What is this article?
Filter Funnel, Conical, 25 ml, Por. 5 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.
