Description
Filter plate, Ø 90 mm, Por. 2 is a circular glass filter intended for laboratory solid–liquid separation. With a diameter of 90 mm and porosity grade 2, the plate provides a fritted glass filtration surface appropriate for routine preparative and analytical applications. Supplied as a single piece, it fits common laboratory filtration assemblies and holders designed for 90 mm discs. Classified as a glass filter under the registered trademark Rettberg ®, the item originates from manufacturer Rettberg and belongs to the filter-plates product group. The porosity-2 designation corresponds to a finer frit structure often chosen when smaller particles must be retained while still permitting practical flow rates. Glass construction affords the chemical resistance and thermal stability typical of laboratory fritware, enabling repeated use after suitable cleaning. The plate can be mounted in funnels, adapters or custom glass apparatus where a durable, reusable filter medium is preferred. Its standardised 90 mm diameter supports straightforward replacement and inventory management. This filter plate is intended for professional laboratory environments that require consistent frit performance without additional coatings or membranes.

Questions about Filter Disk, Ø 90 mm, Por. 2
What is this article?
Filter Disk, Ø 90 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.
