Description
VitraPOR® glass filter plate in borosilicate 3.3 is a round, centred laboratory filter disc with a diameter of 280 mm and porosity grade 1. Nominal thickness is 26,0 mm with a tolerance of ± 6,0 mm, and the surface is untreated for direct use in filtration assemblies. This porous glass medium supports solid–liquid separation and related preparative work where a defined porosity grade and large working diameter are required. Borosilicate 3.3 provides the chemical durability and thermal behaviour expected of this glass type in analytical and process environments. From manufacturer ROBU - Stereon, the VitraPOR® plate combines porosity 1 characteristics with a robust disc geometry suited to coarser filtration duties. The round, centred form aids consistent seating in compatible holders or custom apparatus. Supplied as a single piece, it is intended for laboratory and technical setups that need a 280 mm glass filter plate of porosity 1 without surface treatment, ready for integration into filtration workflows.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 280 mm, Por. 1 Thickness 26 mm ± 6.0 mm
What is this article?
Filter Disc, centered, 280 mm, Por. 1 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.
