Description
VitraPOR® glass filter plate with Ø 300 mm and porosity 2 is a round filtration disc manufactured from borosilicate 3.3 glass. Thickness is given as 26,0 mm with a tolerance of ± 6,0 mm. The surface is untreated and the plate is round-centred, enabling reliable placement in laboratory filtration equipment that requires a glass filter element of this diameter and pore class. Porosity grade 2 defines the pore classification of the disc as stated in the product specification, supporting clear differentiation from other porosity grades in the same diameter series. The untreated surface remains in native glass condition for uses that do not call for coated or specially finished faces. Supplied as 1 piece, the filter plate is intended for analytical and preparative filtration setups where a borosilicate 3.3 VitraPOR® disc of 300 mm diameter and porosity 2 is required. Offered from manufacturer ROBU - Stereon as part of the VitraPOR® glass filter plate range, it suits laboratory workflows that depend on standardised round filter plates with documented porosity and dimensional tolerances for consistent apparatus configuration and selection.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, centered, 300 mm, Por. 2 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.
