Description
Magnetic funnel for MF3/3a, 300 ml is a replacement or spare PES funnel intended for the MF3 and MF3a magnetic filter-holder systems. Manufactured from polyethersulfone, the funnel holds 300 ml and carries 50 ml graduations for straightforward volume reading during vacuum filtration. The magnetic design ensures quick, secure attachment to the matching filter-holder adapter, facilitating membrane changes and reliable sealing under vacuum. This component is used in laboratory vacuum filtration, including Witt-type filtration apparatus setups, for sample preparation, clarification and particulate removal. Supplied as a single piece from manufacturer Witeg, the funnel integrates directly with existing MF3/3a assemblies without additional adapters. Net weight is 0,1 kg. The PES material provides good chemical resistance for aqueous buffers and many common laboratory solvents, making the funnel a practical spare part for busy filtration benches that rely on the MF3 series magnetic holders.

Questions about Magnetic funnel for MF3/3a 300 ml
What is this article?
Magnetic funnel for MF3/3a 300 ml is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Filtration accessories, inside Filtration, in Lab consumables.
Filtration accessories are the holders, the gaskets, the manifolds and the flasks a membrane or a Büchner setup needs. A holder for 47 mm discs does not clamp a 25 mm disc. The gasket is what actually seals.
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.
