Description
VitraPOR® glass filter plate is a biplanar disc manufactured from borosilicate glass 3.3 with a diameter of 100 mm, porosity grade 3 and a thickness of 6,8 mm with a tolerance of ± 0,2 mm. Both faces are precision-ground to deliver exact thickness and a plane-parallel surface, ensuring reliable sealing and uniform filtration performance. The inert borosilicate 3.3 material offers high chemical resistance and thermal stability for demanding laboratory filtration tasks. This filter plate from manufacturer ROBU - Stereon is supplied as a single piece and is well suited for incorporation into custom filter assemblies, vacuum filtration setups or specialized apparatus requiring defined pore characteristics. The controlled porosity and dimensional accuracy support reproducible results in analytical and preparative workflows where consistent flow and particle retention are essential.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, bi-plane, 100 mm, Por. 3 Thickness 6.8 mm ± 0.2 mm
What is this article?
Filter Disc, bi-plane, 100 mm, Por. 3 Thickness 6.8 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.
