Description
Filter plate, Ø 70 mm, Por. 3 is a glass filter disc intended for laboratory filtration work. This circular plate has a diameter of 70 mm and is specified with porosity grade Por. 3, corresponding to the product type Glasfilter. It is supplied as a single piece and carries the registered trademark Rettberg ®. Laboratories use such filter plates as porous glass media within filtration assemblies for solid-liquid separation tasks in analytical, preparative and routine chemical workflows. The defined diameter allows straightforward integration into matching glassware or filter holders that accept a 70 mm disc. Porosity Por. 3 characterises the pore structure of the fritted glass, guiding selection according to the particle retention needs of the application. Offered by manufacturer Rettberg, the plate belongs to the filter-plates category and provides a standardised glass-filter component for research, quality-control and teaching laboratories that require a reliable Por. 3 disc of this size. Its simple format supports both single-use and reusable filtration setups depending on the protocol employed.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disk, Ø 70 mm, Por. 3
What is this article?
Filter Disk, Ø 70 mm, Por. 3 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.
