Description
VitraPOR® biplanar glass filter plate is a precision sintered disc in borosilicate glass 3.3 with a diameter of 300 mm, porosity 0 and a thickness of 18,0 mm ± 0,5 mm. Both faces are ground to deliver exact thickness and a plane-parallel surface, supporting uniform filtration performance and reliable seating in apparatus. This format is intended for laboratory filtration assemblies that require a large-diameter, mechanically stable glass frit with defined porosity. Supplied as one piece from manufacturer ROBU - Stereon, the plate suits preparation, clarification and support roles where chemical resistance and dimensional accuracy matter. Borosilicate 3.3 construction provides thermal and chemical durability typical of laboratory glassware, while the biplanar ground finish helps maintain flat contact surfaces. Choose porosity 0 when coarser retention characteristics are specified for the process. The controlled thickness tolerance supports reproducible installation in holders and custom glass systems used across analytical and preparative work.

Questions about Filter Disc, bi-plane, 300 mm, Por. 0 Thickness 18.0 mm ± 0.5 mm
What is this article?
Filter Disc, bi-plane, 300 mm, Por. 0 Thickness 18.0 mm ± 0.5 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.
