Description
VitraPOR® glass filter plate, 290 mm diameter, porosity 4, is a round sintered disc manufactured from borosilicate glass 3.3. Nominal thickness is 26,0 mm with a tolerance of ± 6,0 mm. The plate has an untreated surface and a round, centred geometry for stable placement in filtration equipment. This VitraPOR® filter plate from manufacturer ROBU - Stereon supports laboratory filtration duties that call for a finer pore grade together with the chemical durability of borosilicate 3.3. Porosity 4 is selected when a tighter pore structure is needed for finer particle retention in analytical or preparative work. The untreated face allows conventional mounting without extra surface treatment. Delivered as one piece, the 290 mm disc fits large-format holders, custom glass assemblies and related filtration setups. Centred round form promotes even seating and consistent flow across the filter area. The product is suited to research, quality-control and process environments that use sintered glass filter media for controlled solid–liquid separation.

Questions about Filter Disc, centered, 290 mm, Por. 4 Thickness 26 mm ± 6.0 mm
What is this article?
Filter Disc, centered, 290 mm, Por. 4 Thickness 26 mm ± 6.0 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.
