Description
neochrom® short-thread screw cap ND9 is a red polypropylene closure with short thread 9-425 and a 6 mm centre hole, fitted with a natural rubber/TEF septum. The septum thickness is 1,0 mm, supporting reliable resealing and making the cap well suited to repeated injections in routine chromatography workflows. Temperature resistance spans −40 °C to +120 °C, covering typical GC and HPLC sample-handling conditions. This ND9 format is a standard screw closure for autosampler vials used in gas and liquid chromatography, where a durable PP shell and a rubber/TEF laminate septum help maintain seal integrity between injections. Supplied in packs of 100 pieces from manufacturer neolab - Labor, the red cap with red-orange/TEF septum is easy to identify on the bench and integrates into established ND9 short-thread vial systems. Ideal for laboratories that need a consistent, multi-injection-ready closure for analytical sample preparation and chromatographic analysis without changing vial platform.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about neochrom® short-thread screw cap ND9, PP red with hole
What is this article?
neochrom® short-thread screw cap ND9, PP red with hole is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
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.
