Description
VitraPOR® glass filter plate is a precision sintered disc made from borosilicate glass 3.3 with a diameter of 30 mm, porosity grade 2, and a thickness of 3,5 mm (± 0,8 mm). The round, centred plate features an untreated surface and is designed for laboratory filtration assemblies requiring defined pore characteristics. Suitable for integration into filter holders, crucibles, or custom glassware setups, it provides reliable particulate retention according to porosity 2 specifications. Offered by manufacturer ROBU - Stereon, these filter plates are supplied in packs of 10 pieces for convenient laboratory stocking. The borosilicate 3.3 construction ensures chemical resistance and thermal stability typical of this glass type, making the plates appropriate for a range of aqueous and organic filtration tasks in analytical chemistry, sample preparation, and research applications. Dimensions and porosity are tightly controlled to support reproducible filtration performance in routine and specialised laboratory workflows.

Questions about Filter Disc, centered, 30 mm, Por. 2 Thickness 3.5 mm ± 0.8 mm
What is this article?
Filter Disc, centered, 30 mm, Por. 2 Thickness 3.5 mm ± 0.8 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 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.
