Description
VitraPOR® glass filter plate in borosilicate 3.3 with a diameter of 20 mm, porosity 1 and thickness of 3,0 mm ± 0,7 mm is a precision sintered disc for laboratory filtration. The untreated surface is round and centred to ensure uniform seating and consistent flow. This filter plate from manufacturer ROBU - Stereon utilises chemically resistant borosilicate glass 3.3 that withstands typical thermal and solvent conditions encountered in analytical work. Porosity grade 1 delivers a defined pore structure suitable for medium-retention filtration tasks. Supplied in a pack of 10 pieces, the plates integrate readily into standard filter funnels, crucibles and apparatus requiring 20 mm discs. The centred geometry and controlled thickness tolerance support reproducible assembly and reliable particle retention across repeated use cycles in chemical, pharmaceutical and research laboratories.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 20 mm, Por. 1 Thickness 3.0 mm ± 0.7 mm
What is this article?
Filter Disc, centered, 20 mm, Por. 1 Thickness 3.0 mm ± 0.7 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.
