Adapter for septum cap; ND9 is a precision laboratory component engineered for reliable connection to short-thread ND9 septum caps in analytical and sample-preparation workflows. Fabricated entirely from polytetrafluoroethylene (PTFE), the adapter delivers outstanding chemical inertness and resistance to a broad spectrum of solvents, acids and bases commonly encountered in chromatography, spectroscopy and general laboratory practice. The short-thread ND9 geometry ensures a secure, leak-resistant fit with standard septum closures, supporting consistent sealing performance during storage, transport or instrumental analysis. Its compact single-piece design simplifies integration into existing vial and bottle systems while maintaining the high purity standards required for sensitive applications. Supplied by manufacturer SCAT, this PTFE adapter is particularly valued where metal-free or highly inert fluid paths are mandatory. The material’s low surface energy further minimises analyte adsorption, helping preserve sample integrity throughout handling steps. Ideal for research, quality-control and routine laboratory environments that demand durable, chemically stable thread adapters.

Questions about Adapter, for septum cap; ND9
What is this article?
Adapter, for septum cap; ND9 is the article on this page. Luminix Health distributes SCAT for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labmateriaal.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
