Description
VitraPOR® glass filter plate, 230 mm, porosity 1, thickness 19 mm ± 4,0 mm is a round, centred sintered disc intended for laboratory filtration and related flow applications. Made from borosilicate glass 3.3, it delivers the chemical durability and thermal stability characteristic of this glass grade in research and quality-control environments. The plate has a diameter of 230 mm and a nominal thickness of 19,0 mm with a tolerance of ± 4,0 mm, forming a substantial porous element for custom holders, large filter funnels or process-scale assemblies. Porosity grade 1 provides a defined intermediate pore range for controlled retention and flow. The surface remains untreated and the disc is round and centred for straightforward mounting or sealing. This VitraPOR® filter plate from manufacturer ROBU - Stereon is offered as one piece, ready for incorporation into glassware, filtration trains or specialised apparatus that call for a large-format porosity 1 sintered plate in borosilicate 3.3.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 230 mm, Por. 1 Thickness 19 mm ± 4.0 mm
What is this article?
Filter Disc, centered, 230 mm, Por. 1 Thickness 19 mm ± 4.0 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.
