Description
Filter plate, Ø 120 mm, Por. 4 is a glass filter plate for laboratory filtration duties. It presents a diameter of 120 mm paired with porosity grade Por. 4, establishing a well-defined glass filter medium for separation tasks that demand this particular size and porosity. Classified as a glass filter, the plate forms part of the filter-plates category routinely employed in laboratory solid–liquid filtration. The unit is supplied as 1 pc, delivering a single circular filter element that can be fitted into filtration assemblies, funnels or related glass apparatus specifying a 120 mm Por. 4 plate. This glass filter plate comes from manufacturer Rettberg and carries the registered trademark Rettberg ®. Its placement within laboratory filtration product coding underscores its role as a discrete, ready-to-use filtration component. The combination of 120 mm diameter and Por. 4 porosity furnishes a practical working surface for laboratory procedures that call for precisely these dimensions and grade. Laboratories requiring an Ø 120 mm Por. 4 glass filter plate therefore receive a component whose format aligns directly with standard apparatus and protocol needs.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disk, Ø 120 mm, Por. 4
What is this article?
Filter Disk, Ø 120 mm, Por. 4 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.
