Description
VitraPOR® glass filter plate, biplane type, 20 mm diameter with porosity 5 and thickness 2,5 mm ± 0,2 mm is a precision filtration component manufactured from borosilicate glass 3.3. The plate features ground faces that provide exact thickness together with a plane-parallel surface, enabling consistent seating and dependable filtration behaviour in laboratory glassware systems. Available in packs of 10 pieces from manufacturer ROBU - Stereon, this filter plate is designed for applications that require a finer controlled pore size and high dimensional accuracy. The biplane geometry combined with porosity grade 5 supports analytical and preparative separation work where uniform flow characteristics and mechanical stability are important. Borosilicate 3.3 construction delivers the chemical resistance and thermal performance expected in everyday laboratory environments. The tight thickness tolerance of ± 0,2 mm promotes reproducible fit across multiple assemblies, while the ground surfaces ensure clean sealing interfaces. Suitable for integration into custom filtration apparatus or standard glass filter holders that call for precise, durable frit elements of porosity class 5.

What is this article?
Filter Disc, bi-plane, 20 mm, Por. 5 Thickness 2.5 mm ± 0.2 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.
