Description
The VitraPOR® quartz glass filter plate is a biplanar disc of amorphous quartz glass with a diameter of 120 mm, porosity grade 3 and a thickness of 8,0 mm ± 0,2 mm. Part of the Series Q range, it features surfaces ground on both sides to give flat, parallel faces that support accurate seating and sealing in laboratory filter assemblies. Amorphous quartz glass provides high chemical inertness and thermal stability, making the plate suitable for demanding filtration, separation and sample-preparation work where dimensional consistency and media purity are essential. Offered as a single piece from manufacturer ROBU - Stereon, this filter plate integrates into holders, funnels and custom glass apparatus used in analytical chemistry, materials research and quality-control workflows. The controlled thickness tolerance of ± 0,2 mm and defined 120 mm diameter help ensure reproducible installation and method transfer. Porosity grade 3 is commonly selected for laboratory separations that require finer retention characteristics while maintaining practical flow. The biplanar geometry simplifies alignment in multi-component setups and supports reliable performance across routine and specialised filtration tasks that rely on robust, high-purity quartz glass media.

Questions about Quartz Glass Filter Disc, bi-plane, 90 mm, Por. 3 Thickness 8.0 mm ± 0.2 mm
What is this article?
Quartz Glass Filter Disc, bi-plane, 90 mm, Por. 3 Thickness 8.0 mm ± 0.2 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.
