Description
Filter plate Ø 30 mm P3 is a laboratory filter plate with a diameter of 30 mm and porosity grade P3. This sintered filter disc is intended for solid–liquid separation and related filtration steps in analytical, research and quality-control workflows. The plate is supplied as a single piece and presents a compact form factor with a net weight of 0,004 kg and a matching gross weight of 0,004 kg, making it straightforward to handle and integrate into glass filtration assemblies. Porosity designation P3 defines the pore-size class of the disc, allowing selection according to the particle retention required by the method. Produced by manufacturer Witeg in Germany (Baden-Württemberg), the component belongs to the filter-plates category used throughout laboratory glassware systems. Its 30 mm diameter suits standard holders and apparatus of corresponding size. The unit supports routine sample clarification, precipitate collection and preparatory filtration where a defined porous medium is needed. Consistent geometry and porosity grading help maintain reproducible laboratory practice across successive runs.

Questions about Sintered discs, 30 mm diam. P 3
What is this article?
Sintered discs, 30 mm diam. P 3 is the article on this page. Luminix Health distributes Witeg 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.
