Description
VitraPOR® biplanar glass filter plate with a diameter of 30 mm, porosity 5 and thickness of 3,0 mm ± 0,2 mm is manufactured from borosilicate 3.3 glass. The surfaces are ground to deliver exact thickness and a plane-parallel finish, ensuring uniform filtration characteristics. This filter plate is suited to laboratory filtration applications requiring defined porosity and dimensional precision. Supplied in packs of 10 pieces, the VitraPOR® plate maintains consistent geometry for reliable performance in filtration assemblies. Produced by manufacturer ROBU - Stereon, the biplanar design with porosity grade 5 supports controlled particle retention and flow. The tight thickness tolerance of ± 0,2 mm together with the ground, plane-parallel faces contributes to reproducible results in analytical and preparative work. The 30 mm diameter format fits standard laboratory filter holders and apparatus, making the plate a practical component for filtration tasks that demand borosilicate glass durability and precise porosity control.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, bi-plane, 30 mm, Por. 5 Thickness 3.0 mm ± 0.2 mm
What is this article?
Filter Disc, bi-plane, 30 mm, Por. 5 Thickness 3.0 mm ± 0.2 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.
