Description
VitraPOR® biplanar glass filter plate is a precision filtration disc made from borosilicate glass 3.3, with a diameter of 160 mm and porosity grade 3. Thickness is specified at 9,5 mm with a tolerance of ± 0,5 mm. Both faces are ground to give exact thickness and a plane-parallel surface, supporting uniform contact and controlled flow in laboratory filter assemblies. Offered as a single piece from manufacturer ROBU - Stereon, this plate is intended for integration into filter apparatus, frit supports and custom glassware where defined porosity and dimensional accuracy matter. The biplanar geometry with carefully finished surfaces aids sealing and reproducible mounting. Porosity 3 addresses finer filtration tasks typical of chemical, analytical and preparative work. Borosilicate 3.3 construction underpins the chemical and thermal behaviour expected of VitraPOR® glass filter media. Use this disc where a stable, plane-parallel porous element of 160 mm diameter is required for routine or specialised separation steps in the laboratory.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, bi-plane, 160 mm, Por. 3 Thickness 9.5 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.
