Description
VitraPOR® biplanar glass filter plate is a precision filtration disc made from borosilicate glass 3.3 for laboratory use. It features a diameter of 150 mm, porosity grade 3 and a controlled thickness of 8,5 mm with a tolerance of ± 0,5 mm. Both faces are ground to deliver exact thickness and a plane-parallel surface, supporting uniform seating in filter apparatus and reproducible filtration geometry. This single-piece plate from manufacturer ROBU - Stereon is intended for setups that rely on defined glass frit porosity and dimensional accuracy. Borosilicate 3.3 is the established glass type for chemical laboratory ware, combining mechanical stability with resistance suited to standard filtration workflows. Porosity 3 designates a finer pore class selected when tighter retention is required in laboratory filtration duties. The biplanar, plan-parallel construction aids mounting in holders and assemblies where flat contact surfaces are essential. Laboratories can integrate the disc into custom or standard filtration systems that call for a robust VitraPOR® glass filter plate of 150 mm diameter with defined porosity and thickness control.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, bi-plane, 150 mm, Por. 3 Thickness 8.5 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.
