Description
VitraPOR® glass filter plate is a round, centred disc of borosilicate 3.3 glass with a diameter of 65 mm, porosity grade 3 and a thickness of 5,5 mm ± 1,3 mm. The untreated surface retains the inherent characteristics of the glass, making the plate appropriate for laboratory filtration systems that demand defined pore size and mechanical stability. It seats readily in standard filter apparatus for gravity or vacuum filtration, clarification and sample work-up. Offered in a pack of five pieces, the discs deliver uniform geometry for consistent performance across multiple setups. Manufactured by ROBU - Stereon, this VitraPOR® filter plate pairs the chemical durability of borosilicate 3.3 with porosity class 3, supporting everyday use with common laboratory solvents and aqueous solutions. The round, centred design ensures reliable positioning in holders and glassware. Suitable for laboratories requiring untreated glass filter media in the porosity 3 range without coatings or further surface modification.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 65 mm, Por. 3 Thickness 5.5 mm ± 1.3 mm
What is this article?
Filter Disc, centered, 65 mm, Por. 3 Thickness 5.5 mm ± 1.3 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.
