Description
VitraPOR® glass filter plate manufactured from borosilicate 3.3 with a diameter of 5 mm, porosity 5 and thickness of 2,8 mm ± 0,7 mm. The surface is untreated and the plate is round and centred. This filter plate from manufacturer ROBU - Stereon is supplied in packs of 10 pieces for laboratory filtration work. The specified porosity grade 5 and precise dimensional tolerances support consistent use in matching filter holders and apparatus. Borosilicate 3.3 glass forms the base material, while the untreated surface retains the native glass finish without coatings. Round centring assists uniform seating during assembly. The compact 5 mm diameter suits small-scale filtration setups common in analytical and research laboratories. Thickness control within ± 0,7 mm helps maintain reliable fit across multiple units. These VitraPOR® plates belong to the standard range of glass filter components used for sample preparation and separation tasks. The pack of 10 pieces allows convenient laboratory stock handling and replacement.

What is this article?
Filter Disc, centered, 5 mm, Por. 5 Thickness 2.8 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.
