Description
VitraPOR® conical filter candle is a sintered glass filtration element made from borosilicate 3.3 for laboratory use. It measures 25 mm in diameter and 65 mm in height, features porosity grade 3, and is fitted with a glass tube of 13 mm diameter, giving a total length of 210 mm. The conical geometry supports controlled liquid filtration and straightforward integration into glass apparatus. Porosity 3 provides a defined pore structure suited to medium filtration tasks where reproducible particle retention is required. Borosilicate 3.3 delivers the chemical resistance and thermal stability expected in routine analytical and preparative work. The integrated glass stem simplifies mounting in filtration assemblies commonly used in chemistry and life-science laboratories. Supplied as a pack of 2 pieces from manufacturer ROBU - Stereon, this VitraPOR® filter candle is intended for workflows that need durable glass filter elements with standardised dimensions and porosity. It is a practical choice for repeated filtration setups where reliable flow and mechanical robustness matter.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Candle, Conical Ø 25 mm, H 65 mm, Por. 3, with Tube 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.
