Description
VitraPOR® biplanar glass filter plate, 70 mm diameter, porosity 00 and thickness 4,5 mm ± 0,2 mm is a precision filtration component manufactured from borosilicate 3.3 glass. The plate features ground faces that deliver exact thickness control and a plane-parallel surface, ensuring uniform contact and reliable sealing within laboratory glassware assemblies. Porosity grade 00 provides a defined pore structure suited to coarser filtration duties. Supplied in packs of five pieces from manufacturer ROBU - Stereon, these non-sterile filter plates are intended for general laboratory use where dimensional accuracy and chemical resistance of borosilicate 3.3 are required. The biplanar geometry and tightly toleranced thickness of 4,5 mm ± 0,2 mm facilitate reproducible installation in filtration apparatus. Ground surfaces minimise irregularities and support consistent flow characteristics across the 70 mm diameter. Originating from Germany, the VitraPOR® filter plate meets the expectations of scientific environments that rely on durable glass frits for sample preparation, solvent handling and routine separation tasks. Its robust construction and precise finishing make it a practical choice for repeated laboratory filtration work.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, bi-plane, 70 mm, Por. 00 Thickness 4.5 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.
