Description
VitraPOR® conical filter candle Ø 25 mm, porosity 3, height 65 mm is a precision laboratory filtration element manufactured from borosilicate glass 3.3. The conical geometry combined with a defined porosity grade 3 and an internal bore of 17,5 mm supports controlled filtration and gas-dispersion duties in analytical and preparative setups. With an outer diameter of 25 mm and overall height of 65 mm, the candle fits common laboratory holders and assemblies used for clarifying suspensions, supporting catalyst beds or introducing gases into liquids. Borosilicate 3.3 construction provides the thermal and chemical resistance expected in routine wet-chemistry and process-development work. These filter candles from manufacturer ROBU - Stereon are supplied as a practical two-piece pack, enabling parallel experiments or ready replacement. Ideal for research, quality-control and teaching laboratories that require reproducible porous-glass components with standardised dimensions and porosity for filtration and sparging applications.
This article is part of Sintered glass filter plates & discs, in Filtration.

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