Description
Filter plate, Ø 30 mm, Por. 2 is a circular glass filter intended for laboratory filtration duties. This sintered glass component offers a diameter of 30 mm together with porosity grade 2, allowing controlled separation of solids from liquids in analytical and preparative workflows. Classified as a Glasfilter product type, the plate integrates readily into filter funnels, crucibles or custom glass apparatus for gravity or vacuum filtration. Supplied as a single piece, it bears the registered trademark Rettberg ® and originates from manufacturer Rettberg. The 30 mm format matches common laboratory holders and joint systems, supporting residue collection, sample clarification and routine clean-up steps across chemistry, biology and materials laboratories. Porosity 2 provides a finer pore structure within the standard frit series, suited to applications needing improved particle retention. The robust glass construction provides broad chemical compatibility with typical laboratory solvents and reagents, making the plate a practical consumable for everyday filtration tasks in research and quality-control environments.

Questions about Filter Disk, Ø 30 mm, Por. 2
What is this article?
Filter Disk, Ø 30 mm, Por. 2 is the article on this page. Luminix Health distributes Rettberg 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.
