Description
VitraPOR® glass filter plate made from borosilicate 3.3, with a diameter of 240 mm, porosity grade 1 and a thickness of 19,0 mm (tolerance ± 4,0 mm). The plate is round and centred with an untreated surface, intended for integration into laboratory filtration assemblies and apparatus that require a robust sintered glass disc. Porosity 1 corresponds to a coarser filtration grade suitable for pre-filtration steps or retention of larger particles in chemical and analytical workflows. Borosilicate 3.3 glass provides the chemical resistance and thermal stability expected in demanding laboratory environments. Supplied as a single piece from manufacturer ROBU - Stereon, this filter plate supports custom setups under vacuum or pressure differentials typical of glass filtration systems. The substantial wall thickness of about 19 mm contributes to mechanical durability during handling and repeated use. Ideal for laboratories that specify VitraPOR® sintered glass components for reliable, chemically resistant filtration performance in research and process development.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 240 mm, Por. 1 Thickness 19 mm ± 4.0 mm
What is this article?
Filter Disc, centered, 240 mm, Por. 1 Thickness 19 mm ± 4.0 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.
