Description
VitraPOR® glass filter plate is a circular borosilicate 3.3 disc for laboratory filtration assemblies. With a diameter of 140 mm and porosity grade 2, it offers a defined pore structure for filtration work that requires this intermediate grade. Thickness is 10,0 mm with a tolerance of ± 2,2 mm, giving a stable plate body for mounting in holders, funnels and custom glassware. The surface is untreated and the plate is round and centred for even seating in assembled systems. Borosilicate 3.3 glass provides the chemical and thermal resistance expected of laboratory glass media under standard conditions. This filter plate from manufacturer ROBU - Stereon is supplied as one piece within the VitraPOR® glass filter range. Porosity grade 2 supports reproducible retention behaviour when the disc is integrated into sintered-glass style filtration setups. The 140 mm format suits larger apparatus where a robust, inert glass filter medium with clearly specified porosity and dimensional tolerance is required for sample preparation, clarification or general laboratory filtration.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 140 mm, Por. 2 Thickness 10 mm ± 2.2 mm
What is this article?
Filter Disc, centered, 140 mm, Por. 2 Thickness 10 mm ± 2.2 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.
