Description
VitraPOR® edge-fused glass filter plate is a precision sintered disc for laboratory solid-liquid separation. Fabricated from borosilicate glass 3.3, it combines chemical resistance with thermal stability suited to routine analytical and preparative work. The plate has an overall diameter of 50 mm, porosity grade Por. 3, a nominal width (NW) of 43 mm and a thickness of 4,5 mm ± 0,2 mm. Its edge-fused rim forms a sealed, reinforced periphery that eases mounting and improves mechanical integrity inside filter holders, funnels and custom glass assemblies. Porosity grade 3 supports efficient retention of fine particles while maintaining practical filtrate flow under vacuum or gravity. This component from manufacturer ROBU - Stereon is supplied as a single piece and integrates readily into standard filtration setups, gas-washing devices and specialised apparatus. Consistent pore structure and a durable borosilicate matrix make it suitable for sample clarification, precipitate collection and solvent filtration in research and quality-control laboratories. The robust construction withstands typical laboratory cleaning regimes, supporting reliable reuse when handled according to good laboratory practice.

What is this article?
VitraPOR® glass filter plate, edge-fused, 50 mm, Por. 3, NW 43 mm, thickness 4.5 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.
