Description
VitraPOR® glass filter plate, 190 mm, porosity 0, thickness 15 mm ± 3,5 mm is a round, centred sintered disc made from borosilicate glass 3.3. With an untreated surface and a diameter of 190 mm, this porosity 0 plate serves laboratory filtration assemblies that need a robust glass frit of defined pore class. Thickness is specified as 15,0 mm with a tolerance of ± 3,5 mm, supporting secure seating in filter apparatus and holders. Borosilicate 3.3 provides the chemical resistance and thermal stability expected in analytical and preparative glass filtration work. The plate is supplied as one piece, non-sterile as delivered, and ready for incorporation into custom filter setups or glassware. Porosity grade 0 represents the coarsest standard frit class, suitable for prefiltration or as a support for finer media depending on the method. This VitraPOR® filter plate from manufacturer ROBU - Stereon is a clear dimensional component for laboratories that specify diameter, porosity and thickness with controlled tolerances. Round geometry and centred finish simplify alignment during installation in filtration equipment across routine and specialised glass filtration tasks.

What is this article?
Filter Disc, centered, 190 mm, Por. 0 Thickness 15 mm ± 3.5 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.
