Description
neochrom® Screw Cap ND9 Short Thread is a white polypropylene closure for analytical vials that need secure sealing with ready needle access. It uses the ND9 short-thread 9-425 format with a 6 mm centre hole and a silicone white/PTFE red septum of 1,0 mm thickness, intended for single-injection use. The assembly withstands temperatures from −60 °C to +200 °C, covering typical cold storage through heated injection conditions in routine chromatography work. Packaged as 100 pc(s), the open-top design supports manual or autosampler syringe penetration while the PTFE face limits analyte interaction and the silicone layer aids resealing after puncture. Suitable for GC and HPLC sample introduction, quality-control sequences and general laboratory vial handling, this short-thread ND9 cap integrates with common vial systems. Offered by manufacturer neolab - Labor, it provides a practical consumable choice where consistent hole geometry, defined septum build-up and colour-coded white PP housings simplify daily sample preparation and injection workflows.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about neochrom® Schraubkappe ND9 Kurzgewinde, PP weiß mit Loch, Silikon weiß/PTFE rot,
What is this article?
neochrom® Schraubkappe ND9 Kurzgewinde, PP weiß mit Loch, Silikon weiß/PTFE rot, is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
