Description
Adapter with flange and NS 45 is a precision glass intermediate piece designed to connect filtration components in laboratory vacuum systems. Featuring a flange interface combined with a standard NS 45 ground joint, the adapter enables secure, vacuum-tight coupling between flasks, funnels or other apparatus elements. This accessory belongs to the range of filtration-device components and supports modular assembly of custom vacuum filtration setups. The NS 45 cone or socket geometry ensures compatibility with matching laboratory glassware while the flange provides an additional sealing surface for clamp or gasket fixation. Manufactured by IDL GmbH, the adapter is intended for use in analytical chemistry, sample preparation and preparative filtration workflows where reliable joints are essential. Its compact form factor allows flexible positioning within existing filtration trains without adding excessive height or dead volume. The piece is supplied as a single unit ready for immediate incorporation into Witt-type or similar vacuum filtration assemblies. Suitable for laboratories requiring interchangeable glass connectors that maintain vacuum integrity under continuous operation.

Questions about Intermediate piece with flange and NS 45 for collecting bottle, with vacuum
What is this article?
Intermediate piece with flange and NS 45 for collecting bottle, with vacuum is the article on this page. Luminix Health distributes IDL GmbH 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.
