Description
VitraPOR® glass filter plate, biplanar, is a precision-ground borosilicate 3.3 disc with a diameter of 40 mm, porosity 0 and thickness of 3,5 mm ± 0,2 mm. The surfaces are ground to exact thickness with plan-parallel faces, ensuring uniform filtration performance and reliable sealing in laboratory filter assemblies. Manufactured from high-quality borosilicate glass 3.3, the plate offers excellent chemical resistance and thermal stability for demanding filtration applications. Suitable for use in vacuum filtration apparatus, gas washing bottles and custom glassware setups requiring a defined porosity grade 0 disc. Supplied from manufacturer ROBU - Stereon, these biplanar filter plates provide consistent pore structure and mechanical strength for analytical and preparative work. The precise dimensional tolerance supports reproducible results in chemical, pharmaceutical and research laboratories. Packaged as 10 pieces, the plates are ready for integration into existing filtration systems or glass apparatus requiring standard 40 mm filter discs.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, bi-plane, 40 mm, Por. 0 Thickness 3.5 mm ± 0.2 mm
What is this article?
Filter Disc, bi-plane, 40 mm, Por. 0 Thickness 3.5 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 Consommables.
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.
