Description
VitraPOR® biplanar glass filter plate with diameter 380 mm and porosity 3 is a sintered filter disc made from borosilicate glass 3.3. Nominal thickness is 25,0 mm with a tolerance of ± 0,5 mm. Both faces are ground to give an exact thickness and a plane-parallel surface, supporting accurate seating in filtration assemblies. This large-format plate from manufacturer ROBU - Stereon is intended for laboratory and technical filtration setups that specify a defined VitraPOR® porosity class together with controlled geometry. The biplanar design provides two flat, parallel working faces across the full 380 mm diameter. Porosity grade 3 designates the pore class of the sintered glass filter medium. Combined with the substantial 25,0 mm body thickness, the disc forms a robust filter element where a wide filtration area and dimensional stability are required. Ground, plane-parallel surfaces help maintain uniform contact when the plate is mounted in holders or apparatus. Supplied as a single piece, the product matches the stated VitraPOR® borosilicate 3.3 specification for porosity 3 at Ø 380 mm. The ± 0,5 mm thickness tolerance around 25,0 mm supports reproducible installation in process and laboratory filtration equipment.

What is this article?
Filter Disc, bi-plane, 380 mm, Por. 3 Thickness 25.0 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.
