Adapter, PP for funnel 300 ml PES is a polypropylene intermediate piece intended for connection with 300 ml PES funnels in laboratory vacuum filtration systems. This component belongs to the family of Witt-type filtration apparatus accessories and supports modular assembly of vacuum filtration equipment used in analytical and preparative workflows. Manufactured from polypropylene (PP), the adapter provides a practical interface between compatible funnel and apparatus parts, helping maintain a secure fit during filtration under reduced pressure. It is supplied as a single unit and is suitable as a replacement or expansion part for existing setups that employ 300 ml PES funnels. The piece is offered by manufacturer Witeg and fits within standard laboratory vacuum filtration configurations. Its role is focused on reliable mechanical coupling rather than active filtration media, making it a straightforward hardware element for routine sample processing. Designed for use in research, quality-control and general laboratory environments, the adapter contributes to flexible, reusable Witt filtration apparatus assemblies where polypropylene components are preferred for chemical compatibility and ease of handling.
This article is part of Membrane filters, in Filtration.

Questions about Support screen, PP for funnel 300ml PES
What is this article?
Support screen, PP for funnel 300ml PES is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Membraanfilters, inside Filtratie, in Verbruiksartikelen.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
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.
