Description
Filter plate Ø 50 mm P5 is a laboratory filter plate with a diameter of 50 mm and porosity grade P5, intended for filtration work in analytical and preparative laboratory settings. Supplied as a single piece, the plate has a net weight of 0,004 kg and a gross weight of 0,004 kg, making it a compact component for filtration assemblies and related glassware setups. Its defined diameter and porosity designation support consistent particle retention and flow characteristics when used with compatible filter apparatus. This filter plate from manufacturer Witeg is suited to routine laboratory filtration tasks where a standardised 50 mm format and P5 porosity are required. Originating from Germany (Baden-Württemberg), it belongs to the filter-plate category used across chemical, pharmaceutical and research laboratories. The plain, dimensionally specified design allows straightforward integration into existing filtration workflows without additional adapters beyond those matched to the 50 mm diameter. Researchers and technicians can select this porosity grade when coarser or finer alternatives are not appropriate for the sample matrix under investigation. The product is offered as one piece per unit for flexible stocking and replacement.

Questions about Sintered discs, 50 mm diam. P 5
What is this article?
Sintered discs, 50 mm diam. P 5 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Consommables.
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.
