Description
VitraPOR® glass filter plate is a round, centred filter disc made of borosilicate glass 3.3 with a diameter of 180 mm. It is supplied in porosity grade 1 and has a thickness of 13,0 mm with a tolerance of ± 3,0 mm. The surface of the plate is untreated. This laboratory filter plate is suited to filtration work where a defined porosity class and glass construction are required. From manufacturer ROBU - Stereon, the plate comes as a single piece for use in filtration setups that take an 180 mm disc. The centred round geometry supports reliable seating, and the untreated surface matches the standard finish of this VitraPOR® glass filter plate. Porosity 1 denotes the pore-size class of the disc. Combining borosilicate 3.3, 180 mm diameter, porosity grade 1 and 13,0 mm thickness (± 3,0 mm), it offers a clearly specified filtration element for laboratory apparatus needing an untreated round glass filter plate of this size and grade.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 180 mm, Por. 1 Thickness 13 mm ± 3.0 mm
What is this article?
Filter Disc, centered, 180 mm, Por. 1 Thickness 13 mm ± 3.0 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.
