Description
Filter plate, 210 mm, Por. 1, thickness 19 mm ± 4,0 mm is a VitraPOR® glass filter disc intended for laboratory filtration hardware and frit-based assemblies. The plate is made from borosilicate glass 3.3 and is supplied as a round, centred disc with untreated surface. Key dimensions are a diameter of 210 mm, porosity grade 1 and a thickness of 19,0 mm with a tolerance of ± 4,0 mm, supporting consistent fit in glass apparatus that requires a defined porous medium. Available as a single piece from manufacturer ROBU - Stereon, the filter plate is suited to separation, support and related flow applications in chemical and analytical laboratories. Porosity 1 offers a finer structure than the coarsest grades while remaining appropriate for many standard laboratory filtration tasks. This VitraPOR® component gives glassblowers and lab technicians a clearly specified disc for building or replacing filter elements where diameter, thickness tolerance and porosity must be controlled.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 210 mm, Por. 1 Thickness 19 mm ± 4.0 mm
What is this article?
Filter Disc, centered, 210 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.
