Description
VitraPOR® biplanar glass filter plate with 30 mm diameter and porosity 0 is produced from borosilicate glass 3.3. It offers a defined thickness of 3,0 mm with a tolerance of ± 0,2 mm. Both faces are ground to achieve exact thickness and a plane-parallel surface, supporting consistent seating and filtration performance in laboratory apparatus. This filter plate from manufacturer ROBU - Stereon is intended for use where controlled porosity glass frits are required. The biplanar geometry promotes uniform flow across the filter area. Porosity grade 0 corresponds to the coarsest standard glass filter classification, suitable for preliminary clarification and retention of larger particles. Chemical resistance typical of borosilicate 3.3 makes the plate compatible with a wide range of aqueous and organic media commonly encountered in analytical and preparative workflows. Pack size is 10 pieces, convenient for routine laboratory stocking and replacement. Ground, plane-parallel surfaces help ensure reliable mounting in holders or custom filtration assemblies without additional machining.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, bi-plane, 30 mm, Por. 0 Thickness 3.0 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.
