Filter plate Ø 120 mm P4 is a laboratory filter plate with a diameter of 120 mm and porosity grade P4 intended for fine solid-liquid separation. It provides controlled particle retention and clarification for analytical, preparative and everyday laboratory workflows that benefit from a finer pore structure. Supplied as 1 pc with a net weight of 0,142 kg, the plate can be readily fitted into compatible funnels, holders or custom filtration assemblies. The circular geometry and 120 mm diameter support even distribution of the filtration medium and reliable mechanical seating. Porosity P4 represents a fine-pore designation appropriate for tasks requiring higher retention efficiency while remaining practical for laboratory-scale volumes. Manufactured by Witeg in Germany, the plate is suited to research, quality-control and teaching environments. Common applications encompass collection of fine precipitates, clarification of solutions and assistance in multi-step sample-preparation protocols. Matching porosity grade to the specific sample remains critical for consistent results, and the P4 option addresses finer filtration requirements. The single-unit format simplifies handling, storage and inventory while maintaining the dimensional accuracy needed for dependable laboratory performance across repeated use cycles.

Questions about Sintered disc Ø:120mm P4
What is this article?
Sintered disc Ø:120mm P4 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Verbruiksartikelen.
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.
