Description
VitraPOR® glass filter plate is a rigid sintered filtration disc made from borosilicate glass 3.3 for demanding laboratory and process filtration setups. The round, centred plate measures 380 mm in diameter with porosity grade 4 and a nominal thickness of 38,0 mm (tolerance ± 8,0 mm). An untreated surface preserves the native sintered structure for applications that require a defined porous glass medium rather than coated or modified faces. This single-piece filter plate from manufacturer ROBU - Stereon is intended for integration into filtration apparatus, holders, or custom assemblies where mechanical stability and chemical resistance of borosilicate 3.3 are advantageous. Porosity 4 provides a finer pore class within the VitraPOR® series, supporting clarification and separation tasks that need controlled permeability. The large 380 mm diameter suits higher-throughput or larger-area filtration compared with small laboratory discs. Specify this plate when a robust, untreated borosilicate filter element with porosity 4 and substantial thickness is required for your setup.

What is this article?
Filter Disc, centered, 380 mm, Por. 4 Thickness 38 mm ± 8.0 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.
