Description
VitraPOR® glass filter plate, biplane, is a sintered filtration disc in borosilicate glass 3.3 with a diameter of 250 mm, porosity 0 and a thickness of 15,0 mm (± 0,5 mm). Both faces are ground to deliver exact thickness and a plane-parallel surface, supporting uniform seating and consistent filtration geometry in laboratory assemblies. Porosity grade 0 is intended for coarse filtration and related process steps where open pore structure and chemical durability of borosilicate 3.3 are required. The rigid glass plate format suits integration into filter apparatus, holders or custom set-ups that need a stable, dimensionally defined porous medium rather than flexible membrane media. Manufactured by ROBU - Stereon, this biplane filter plate is supplied as a single piece for laboratory filtration workflows. The combination of defined diameter, controlled thickness tolerance and ground plane-parallel faces helps maintain reproducible mechanical fit and filtration performance across repeated use and cleaning cycles in research and analytical environments.

What is this article?
Filter Disc, bi-plane, 250 mm, Por. 0 Thickness 15.0 mm ± 0.5 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.
