Description
VitraPOR® micro filter candle is a cylindrical borosilicate 3.3 glass filter element intended for precise laboratory filtration. With an outer diameter of 20 mm, porosity grade 4, height of 30 mm and internal bore of 15,5 mm, it offers a compact sintered structure for fine particulate retention and clarification. The VitraPOR® borosilicate 3.3 material delivers the chemical durability and thermal stability expected in analytical workflows. Packaged as 5 pieces and available from manufacturer ROBU - Stereon, these candles fit holders or assemblies that accommodate the 15,5 mm bore. Porosity 4 is suited to finer filtration steps in sample preparation, solvent clean-up or micro-scale separations. The cylindrical geometry ensures straightforward integration into existing glass filtration systems while maintaining consistent flow characteristics. Ready for use in research, quality control and routine laboratory applications requiring reliable inert filter media of defined pore size.

What is this article?
Micro-Filter Candle-blanks, Ø 20 mm, Por. 4, 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.
