Description
Replacement attachment NS 45/40 is a dedicated spare component for vacuum filtration assemblies that use a standard ground joint interface. Designed for DURAN® vacuum filtration units, this attachment restores the upper connection geometry so that filter funnels, adapters and related glassware can again be seated securely on the NS 45/40 joint. The ground joint format supports a reliable seal under reduced pressure, which is essential for routine laboratory filtration, sample clarification and solvent recovery workflows. Supplied as a single piece weighing 0,225 kg, the part is intended as a direct replacement when the original attachment is damaged, worn or missing. It integrates into established filtration setups without changing the overall layout of the apparatus. Manufactured by DWK Life Sciences, the DURAN®-compatible attachment suits teaching, quality-control and research laboratories that maintain modular glass vacuum filtration systems and need standardised spare parts for continuous operation and straightforward maintenance of their filtration hardware.

Questions about Replacement attachment NS 45/40, for vacuum filtration unit, DURAN®, 1 unit(s)
What is this article?
Replacement attachment NS 45/40, for vacuum filtration unit, DURAN®, 1 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences 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.
