Description
Filter plate 220 mm, porosity 1, is a VitraPOR® sintered glass disc made from borosilicate glass 3.3 for laboratory filtration assemblies. The round, centred plate measures 220 mm in diameter with a nominal thickness of 19,0 mm and a tolerance of ± 4,0 mm, giving a robust porous medium for gravity or vacuum filtration setups. Its untreated surface preserves the open sintered structure characteristic of porosity grade 1, suited to coarser particle retention and high flow relative to finer porosity grades. Offered as a single piece from manufacturer ROBU - Stereon, the plate integrates into glass filter apparatus, custom holders and process filtration hardware where chemical resistance and thermal stability of borosilicate 3.3 are required. Typical uses include preparative chemistry, sample clarification, catalyst recovery support and general solid–liquid separation in research and industrial laboratories. The defined diameter and thickness simplify replacement planning and dimensional matching to existing filter housings. Non-sterile supply matches standard glassware practice; users can clean and prepare the disc according to their own protocols before installation in filtration trains.

Questions about Filter Disc, centered, 220 mm, Por. 1 Thickness 19 mm ± 4.0 mm
What is this article?
Filter Disc, centered, 220 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.
