Description
VitraPOR® glass filter plate, biplanar, is a precision sintered disc for laboratory filtration assemblies requiring defined porosity and dimensional accuracy. Manufactured from borosilicate glass 3.3, the plate has a diameter of 170 mm, porosity grade 3 and a thickness of 9,5 mm with a tolerance of ± 0,5 mm. Both faces are ground to deliver exact thickness and a plane-parallel surface, supporting uniform seating in filter holders, Büchner-type setups and custom glass apparatus. The biplanar geometry and controlled pore structure make the disc suitable for clarifying suspensions, separating solids from liquids and integrating into vacuum or gravity filtration workflows where reproducible flow behaviour is important. Offered as a single piece from manufacturer ROBU - Stereon, this non-sterile filter plate is intended for general laboratory use rather than sterile processing. Its robust borosilicate construction withstands typical thermal and chemical conditions of analytical and preparative filtration, providing a reliable frit element for research, process development and quality-control applications that demand a large-diameter Por. 3 glass filter medium with tightly specified thickness.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, bi-plane, 170 mm, Por. 3 Thickness 9.5 mm ± 0.5 mm
What is this article?
Filter Disc, bi-plane, 170 mm, Por. 3 Thickness 9.5 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.
