Description
VitraPOR® glass filter plate is a sintered disc produced from borosilicate glass 3.3, featuring a 30 mm diameter and porosity grade F. Nominal thickness is 3,5 mm with a tolerance of ± 0,8 mm. The plate has an untreated surface and is supplied round and centred for straightforward mounting in filtration hardware. Packaged in units of 10 pieces, it serves laboratory applications that require a defined glass filter medium of porosity F. This VitraPOR® component from manufacturer ROBU - Stereon offers the well-known chemical and thermal performance of borosilicate 3.3 together with controlled pore structure. Porosity F is selected according to the particle retention and flow-rate needs of the method. Uniform dimensions help ensure reliable fit in standard holders, funnels and custom apparatus. Research, quality-control and preparative laboratories employ these plates for filtration, gas dispersion or as support layers within multi-stage assemblies where an inert, untreated glass surface is preferred.
This article is part of Sintered glass filter plates & discs, in Filtration.

What is this article?
Filter Disc, centered, 30 mm, Por. F Thickness 3.5 mm ± 0.8 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.
