Description
VitraPOR® glass filter plate is a round, centred disc of borosilicate glass 3.3 with a diameter of 100 mm, porosity grade 2 and a thickness of 8,0 mm ± 1,8 mm. The untreated surface is ready for integration into laboratory filtration assemblies and sintered-glass apparatus. This plate is offered by manufacturer ROBU - Stereon and combines the chemical resistance and thermal stability typical of borosilicate 3.3. Supplied as 1 pc, it serves analytical chemistry, sample preparation and process filtration tasks that require a defined medium pore structure. Porosity 2 supports reliable particle retention while maintaining practical flow rates. The plate can be mounted in custom filter holders or used as a replacement element in existing glassware systems. Manufactured in Germany (Rhineland-Palatinate), the component retains dimensional accuracy within the stated thickness tolerance and is suitable for repeated laboratory use under standard conditions. Its robust construction and precise geometry make it a practical choice for laboratories that need consistent filtration performance from high-quality borosilicate media.
This article belongs on Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 100 mm, Por. 2 Thickness 8.0 mm ± 1.8 mm
What is this article?
Filter Disc, centered, 100 mm, Por. 2 Thickness 8.0 mm ± 1.8 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 Consommables.
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.
