Description
VitraPOR® biplane filter plate with a diameter of 250 mm and porosity grade 4 is a precision glass filter disc produced from borosilicate glass 3.3. The plate is supplied at a thickness of 15,0 mm with a tolerance of ± 0,5 mm, and both faces are ground to achieve exact thickness and a plane-parallel surface. These dimensional and surface characteristics support reproducible seating in laboratory filter assemblies and consistent filtration performance. Offered by manufacturer ROBU - Stereon, the VitraPOR® disc is intended for solid–liquid separation duties where a defined pore structure and mechanical stability are required. Porosity 4 suits finer filtration steps in analytical, preparative and process-support workflows. The robust borosilicate 3.3 material combines chemical resistance with the thermal behaviour expected of laboratory glassware. Packaged as one piece, this 250 mm biplane filter plate is ready for integration into suitable holders, funnels or custom filtration setups that call for a large-format frit of controlled thickness and planarity.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, bi-plane, 250 mm, Por. 4 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.
