Description
VitraPOR® glass filter plate with 20 mm diameter and porosity 5 is a precision filtration component manufactured from borosilicate 3.3 glass. It features a thickness of 3,0 mm with a tolerance of ± 0,7 mm, an untreated surface and a round centred geometry for reliable seating in laboratory apparatus. This filter plate from manufacturer ROBU - Stereon offers the chemical resistance and thermal stability characteristic of borosilicate 3.3, making it suitable for a wide range of analytical and preparative filtration tasks. Supplied as a single piece, the plate integrates easily into filter funnels, crucibles or custom sintered-glass assemblies. The untreated surface preserves the inherent purity of the glass and avoids any coating-related interactions with solvents or samples. Porosity grade 5 provides a fine pore structure that supports efficient particle retention while maintaining practical flow rates. Laboratory professionals value the consistent dimensional accuracy and robust material properties for routine sample clarification, residue collection and support media applications. The centred round design ensures straightforward mounting and long service life under typical laboratory conditions.

Questions about Filter Disc, centered, 20 mm, Por. 5 Thickness 3.0 mm ± 0.7 mm
What is this article?
Filter Disc, centered, 20 mm, Por. 5 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.
