Description
Micro filter candle Ø 6 mm, porosity 1, height 15 mm with glass tube is a cylindrical VitraPOR® filtration element made of borosilicate glass 3.3 for fine particle separation in laboratory applications. The filter candle itself measures 6 mm in diameter and 15 mm in height at porosity grade 1, connected to a narrow glass tube of 6 mm diameter, giving an overall length of 150 mm. This compact design enables efficient filtration of small sample volumes, gas scrubbing, or sparging operations where space is limited. Produced by ROBU - Stereon, the VitraPOR® sintered glass structure offers excellent chemical resistance and thermal stability typical of borosilicate 3.3. Porosity 1 provides a defined pore range suitable for retaining coarser precipitates while maintaining reasonable flow rates. The integrated glass tube allows easy insertion into flasks, reactors, or custom assemblies. Supplied in packs of 5 pieces, these micro filter candles are ideal for analytical sample preparation, micro-scale synthesis work-up, and specialized filtration tasks in research laboratories requiring durable, reusable glass frit elements.

Questions about Micro-Filter Candle, Ø 6 mm, H 15 mm, Por. 1, with Tube
What is this article?
Micro-Filter Candle, Ø 6 mm, H 15 mm, Por. 1, 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 Consommables.
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.
