Description
VitraPOR® biplanar glass filter plate in borosilicate 3.3 offers a diameter of 100 mm, porosity 5 and thickness of 6,8 mm ± 0,2 mm for precise laboratory filtration. Ground faces provide exact thickness control and a plane-parallel surface, supporting consistent sealing and mounting in filter assemblies. This plate from manufacturer ROBU - Stereon suits applications that require chemical resistance, thermal stability and a defined pore structure. The biplanar geometry ensures uniform contact across the working faces, while porosity grade 5 delivers finer particle retention with practical flow characteristics. Borosilicate 3.3 construction brings the familiar durability expected of laboratory glassware for solid-liquid separation, gas filtration or sample preparation. Dimensional accuracy aids interchangeability in research, quality-control and preparative workflows. Supplied as a single piece, the plate integrates readily into existing apparatus where inert glass media of controlled porosity and geometry are essential.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, bi-plane, 100 mm, Por. 5 Thickness 6.8 mm ± 0.2 mm
What is this article?
Filter Disc, bi-plane, 100 mm, Por. 5 Thickness 6.8 mm ± 0.2 mm is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Plaques filtrantes en verre fritté & disques, inside Filtration, in Consommables.
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.
