Description
VitraPOR® micro filter candle is a cylindrical sintered-glass filter element made from borosilicate glass 3.3, with an outer diameter of 20 mm, porosity grade 2, height of 30 mm and an internal bore of 15,5 mm. Intended for laboratory filtration of liquids and gases, the candle provides a rigid porous wall that supports clarifying, pre-filtration and sample-preparation steps in analytical and preparative workflows. Porosity 2 corresponds to a medium pore range frequently chosen for general laboratory duties where balanced flow and particle retention are required. Borosilicate 3.3 offers high thermal and chemical resistance, allowing use with many aqueous and organic media under typical lab conditions. The defined cylindrical geometry and central bore simplify mounting in compatible holders or assemblies. Packaged as 5 pc(s) and available from manufacturer ROBU - Stereon, these VitraPOR® micro filter candles suit filtration setups, process laboratories and routine sample work where reusable glass filter media are preferred for consistent porosity and straightforward cleaning between runs.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Micro-Filter Candle-blanks, Ø 20 mm, Por. 2, H 30 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.
