Description
VitraPOR® glass filter plate, edge-fused, is a precision laboratory filtration disc made from borosilicate glass 3.3. The plate has an outer diameter of 90 mm, porosity grade 1 and a nominal width (NW) of 80 mm, with a thickness of 6,2 mm (tolerance ± 0,2 mm). Edge-fused construction ensures a sealed perimeter that supports secure mounting in filtration assemblies and reduces bypass. Offered as a single piece from manufacturer ROBU - Stereon, the disc is intended for solid-liquid separation, clarifying steps and sample preparation in analytical and preparative laboratory work. Borosilicate 3.3 provides good chemical resistance and thermal stability for aqueous and many organic media under standard laboratory conditions. The defined porosity grade 1 enables controlled flow rates suitable for coarse to medium filtrations. This edge-fused filter plate integrates into glass filtration apparatus and custom holders where a robust, chemically inert frit of 90 mm diameter is required. Dimensions and material properties make it a reliable component for routine and specialised filtration tasks.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter plate - edge-fused, 90 mm, Por. 1, NW 80 mm, thickness 6.3 mm ± 0.2 mm
What is this article?
Filter plate - edge-fused, 90 mm, Por. 1, NW 80 mm, thickness 6.3 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.
