Description
Filter plate Ø 70 mm P4 is a laboratory filter plate with a diameter of 70 mm and porosity P4. Supplied as 1 pc(s), it has a net weight of 0,025 kg and a gross weight of 0,025 kg. This filter plate belongs to the filter plates category and is produced in Germany, specifically in the Baden-Württemberg region, from manufacturer Witeg. The 70 mm diameter combined with P4 porosity supports standard laboratory filtration requirements where defined pore characteristics are needed. Filter plates of this specification are used in scientific procedures that call for consistent sizing and porosity during separation steps. The circular format integrates readily into common laboratory filtration apparatus. Single-piece supply simplifies inventory handling and allocation across research, analytical and quality-control workflows. The stated dimensions and porosity grade provide the core attributes required for routine filtration tasks in professional laboratory environments. This 70 mm P4 plate offers a straightforward component option matching the listed physical data for everyday lab use.

Questions about Sintered discs, 70 mm diam. P 4
What is this article?
Sintered discs, 70 mm diam. P 4 is the article on this page. Luminix Health distributes Witeg 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.
