Description
VitraPOR® glass filter plate with a diameter of 40 mm, porosity grade 1 and thickness of 4,5 mm ± 1,0 mm is manufactured from borosilicate glass 3.3 for precise laboratory filtration work. The untreated, round and centred surface promotes uniform flow and reliable performance in vacuum filtration, gas washing or porous support applications. Available in packs of 10 pieces, these plates integrate readily into standard glass apparatus and filtration assemblies. Produced by manufacturer ROBU - Stereon, the VitraPOR® series combines chemical resistance with the thermal stability characteristic of borosilicate 3.3. Porosity 1 delivers a defined pore structure appropriate for medium filtration duties. Dimensional tolerances of ± 1,0 mm on thickness ensure consistent fit across laboratory setups. Non-sterile and ready for use, the plates serve research, analytical and process laboratories requiring durable glass filter media of controlled porosity and geometry.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 40 mm, Por. 1 Thickness 4.5 mm ± 1.0 mm
What is this article?
Filter Disc, centered, 40 mm, Por. 1 Thickness 4.5 mm ± 1.0 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.
