Description
Filter funnel, 500 ml, porosity 5 is a laboratory filtration device manufactured from borosilicate 3.3 glass. It features an integrated VitraPOR® filter plate of 95 mm diameter with porosity grade 5 and a working height of 100 mm above the plate, providing a total capacity of 500 ml for solid-liquid separations. This nutsche-style filter funnel supports vacuum or gravity filtration in chemical synthesis, analytical sample preparation, and precipitate collection. The sintered glass plate delivers controlled particle retention while the borosilicate body offers chemical resistance and thermal durability for routine laboratory use. Produced by manufacturer ROBU - Stereon, the funnel integrates readily into standard filtration assemblies and glassware setups. Its robust construction facilitates efficient clarification of solutions and recovery of solids across research, quality-control, and educational environments. The defined porosity grade ensures reproducible filtrate quality, and the generous headspace above the plate accommodates varied sample loads without overflow. Suitable for both aqueous and many organic media, this single-unit filter funnel streamlines everyday filtration workflows while maintaining sample integrity throughout the process.
This article belongs on Sintered glass filter plates & discs, in Filtration.

Questions about Filter Funnel, 500 ml, Por. 5
What is this article?
Filter Funnel, 500 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 Consommables.
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.
