Description
VitraPOR® biplanar filter plate in borosilicate glass 3.3 offers a diameter of 80 mm, porosity grade 00 and a precisely controlled thickness of 5,0 mm with a tolerance of ± 0,2 mm. Both faces are ground to deliver an exact thickness and a plane-parallel surface, ensuring reliable seating and uniform filtration performance in laboratory filtration assemblies. The chemically resistant borosilicate 3.3 glass withstands typical laboratory solvents and thermal conditions encountered in analytical and preparative work. Manufactured by ROBU - Stereon, this VitraPOR® disc is intended for use as a porous support or filter medium in glass filtration apparatus where consistent pore structure and dimensional accuracy are required. The biplanar geometry facilitates even flow distribution across the filtration area. Supplied in packs of five pieces, the plates are ready for integration into custom or standard filter holders. Their robust glass construction provides mechanical stability while maintaining the optical clarity and inertness characteristic of borosilicate laboratory glassware, supporting reproducible results in routine and specialised filtration applications.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, bi-plane, 80 mm, Por. 00 Thickness 5.0 mm ± 0.2 mm
What is this article?
Filter Disc, bi-plane, 80 mm, Por. 00 Thickness 5.0 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.
