Description
Filter plate, biplanar, 130 mm, Por. F is a VitraPOR® glass filter disc in borosilicate 3.3 for laboratory filtration assemblies that require a rigid, dimensionally controlled frit element. The plate has a diameter of 130 mm and porosity grade F, with a defined thickness of 8,0 mm and a tolerance of ± 0,2 mm. Both faces are ground so that thickness is exact and the working surfaces remain plane-parallel, supporting uniform contact, even load distribution and reliable sealing against mating parts. Offered as a single piece from manufacturer ROBU - Stereon, this biplanar filter plate suits holders and apparatus where porosity F and tightly controlled geometry are specified. Borosilicate 3.3 provides the chemical and thermal behaviour expected of laboratory glassware, while the ground, plan-parallel finish helps maintain consistent filtration performance across the full disc area. Select this format when your method calls for a 130 mm biplanar glass filter plate of porosity F and 8,0 mm nominal thickness with close dimensional tolerance.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, bi-plane, 130 mm, Por. F Thickness 8.0 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.
