Description
VitraPOR® micro filter candle is a cylindrical sintered-glass filtration element manufactured from borosilicate glass 3.3. It features an outer diameter of 9 mm, a height of 20 mm and a central bore of 4,5 mm, giving a compact format suited to micro-scale laboratory filtration. Porosity grade 5 defines the pore structure of this candle and supports controlled retention in analytical and preparative work where fine glass filter media are required. The cylindrical VitraPOR® geometry allows straightforward mounting in holders or assemblies that accept small filter candles. Made from borosilicate 3.3, the element combines the dimensional stability and chemical durability associated with this glass type. Packs contain 5 pieces and are offered by manufacturer ROBU - Stereon for routine laboratory supply. These micro filter candles belong to the filter-candle product group and are intended for non-sterile laboratory filtration tasks that benefit from a defined porosity, precise outer dimensions and a through-bore of 4,5 mm. The combination of porosity 5, 9 mm diameter and 20 mm height makes the candle a practical choice when small sintered-glass filter elements are specified in method or apparatus descriptions.

What is this article?
Micro-Filter Candle-blanks, Ø 9 mm, Por. 5, H 20 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.
