Beschrijving
Filter plate Ø 40 mm P1 is a laboratory filtration disc with a diameter of 40 mm and porosity grade P1. It serves solid-liquid separation and related filtration procedures in chemical, analytical and research laboratories. Supplied as a single piece with a net weight of 0,006 kg, the plate fits standard filtration assemblies, funnels and holders used in everyday laboratory work. From manufacturer Witeg, this filter plate delivers defined dimensional accuracy together with a specified P1 porosity for consistent performance. Filter plates of the P1 class are chosen when intermediate filtration characteristics are needed within the compact 40 mm format. The product supports routine sample preparation, precipitate collection and clarification of suspensions in both academic and industrial environments. Its standardised diameter ensures compatibility with matching laboratory apparatus while the graded porosity enables reproducible particle retention. Laboratories appreciate the practical single-unit format that simplifies stock management and workflow organisation. This filter plate contributes to efficient and reliable filtration steps wherever a 40 mm P1 medium is specified.

Questions about Sintered discs, 40 mm diam. P 1
What is this article?
Sintered discs, 40 mm diam. P 1 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.
