Description
Filter plate Ø 25 mm, Por. 0 is a sintered glass filter disc designed for laboratory solid–liquid separations. With a 25 mm diameter and the coarsest porosity grade 0, the plate is well suited to rapid filtration of larger particles, pre-filtration steps or support of finer filter media. Supplied as one piece, it fits standard holders and glass filtration assemblies used under gravity or vacuum. Produced by manufacturer Rettberg and bearing the registered trademark Rettberg ®, this glass filter belongs to the dedicated glass-filter product type. The open pore structure of porosity 0 promotes high flow rates while still retaining coarse solids, making the disc practical for preparatory work, sample clean-up and educational demonstrations. The durable glass construction allows cleaning and repeated use in research, quality-control and teaching laboratories. Compact yet robust, the 25 mm Por. 0 filter plate integrates easily into existing filtration trains and provides a reliable frit medium whenever coarse retention and fast throughput are required.

Questions about Filter Disk, Ø 25 mm, Por. 0
What is this article?
Filter Disk, Ø 25 mm, Por. 0 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.
