Description
VitraPOR® glass filter plate, 10 mm, porosity 2, is a round, centred sintered disc manufactured from borosilicate glass 3.3 for laboratory filtration assemblies. It has a nominal thickness of 2,8 mm with a tolerance of ± 0,7 mm and an untreated surface, giving a defined pore structure of porosity grade 2 for medium filtration duties in analytical and preparative work. Borosilicate 3.3 offers high chemical resistance to common laboratory solvents and good thermal stability when the disc is built into glass apparatus. The standardised 10 mm diameter supports reproducible mounting and sealing in custom filter holders, funnels or fritted glassware. Pack size is 10 pieces from manufacturer ROBU - Stereon. Porosity grade 2 balances flow rate and particle retention for general laboratory use, while the untreated surface allows direct installation or further processing according to local protocols. Consistent dimensional control aids reliable integration into precision glass systems where a compact sintered filter plate is required.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 10 mm, Por. 2 Thickness 2.8 mm ± 0.7 mm
What is this article?
Filter Disc, centered, 10 mm, Por. 2 Thickness 2.8 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.
