Description
VitraPOR® glass filter plate, biplanar, 180 mm, porosity 0, thickness 9,5 mm ± 0,5 mm is a precision sintered filter disc for laboratory filtration assemblies. Made from borosilicate 3.3, the plate is specified with a diameter of 180 mm and porosity grade 0, giving a defined porous structure for filtration and support duties that call for this coarse porosity class. Thickness is controlled at 9,5 mm with a tolerance of ± 0,5 mm, and both faces are ground to deliver exact thickness with a plane-parallel surface. The biplanar, ground finish supports uniform seating in holders and reproducible mechanical fit where parallel faces and consistent strength are important. Supplied as 1 pc, the disc is intended as a replaceable filter plate element in glass filtration setups that accept Ø 180 mm plates. This VitraPOR® filter plate from manufacturer ROBU - Stereon brings borosilicate 3.3 construction together with tightly specified geometry for demanding laboratory filtration hardware. Porosity 0, the 180 mm diameter, and the plane-parallel ground surfaces allow clear matching to apparatus that requires a biplanar glass filter plate of this size and grade.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, bi-plane, 180 mm, Por. 0 Thickness 9.5 mm ± 0.5 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.
