Description
Filter plate, Ø 50 mm, Por. 3 is a sintered glass filter disc intended for laboratory filtration applications. Measuring 50 mm in diameter and featuring porosity grade Por. 3, this glass filter plate supports effective solid-liquid separation in analytical and preparative work. As a Glasfilter product type belonging to the filter plates category, it is compatible with common filtration apparatus found in chemical and biological laboratories. The item is supplied as 1 pc and comes from manufacturer Rettberg under the registered trademark Rettberg ®. Glass construction delivers the chemical resistance and thermal stability required for everyday solvent and sample handling. Porosity designation 3 indicates a finer pore structure appropriate for more demanding filtration steps. Laboratory staff can mount the disc in funnels or filter holders for reproducible particle retention. The simple format allows straightforward replacement during continuous experimental series or quality-control routines that rely on defined glass filtration media.

Questions about Filter Disk, Ø 50 mm, Por. 3
What is this article?
Filter Disk, Ø 50 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.
