Description
VitraPOR® glass filter plate, biplanar, is a precision filtration disc in borosilicate glass 3.3 with a diameter of 300 mm and porosity grade 2. Thickness is specified at 18,0 mm with a tolerance of ± 0,5 mm, so the plate meets tight dimensional requirements in laboratory and process filtration assemblies. Both faces are ground to give exact thickness and a plane-parallel surface, supporting uniform contact, reliable seating and consistent flow across the frit. Offered as a single piece from manufacturer ROBU - Stereon, this biplanar VitraPOR® plate is intended for setups that need a durable glass filter medium with controlled pore structure and reproducible geometry. Porosity 2 suits general clarification and particle-retention duties where a medium pore range is appropriate. Borosilicate 3.3 provides the chemical resistance and thermal behaviour expected of laboratory glassware, allowing use with aqueous media and many common laboratory solvents. The combination of large diameter, defined porosity, ground plane-parallel faces and tight thickness tolerance makes the plate a practical choice for filter holders, custom apparatus and technical filtration work that demand stable, accurately finished glass frit plates.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, bi-plane, 300 mm, Por. 2 Thickness 18.0 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.
