Description
neochrom® Screw Cap Short Thread ND9 is a blue polypropylene screw closure with short thread 9-425 and a 6 mm centre hole for laboratory vials. It incorporates a virgin PTFE septum of 0,2 mm thickness that is high-temperature resistant and intended for single-injection applications. The holed open-top format enables dependable needle access during chromatographic sampling and related analytical work, while the thin virgin PTFE face offers an inert barrier toward the sample headspace. Available in packs of 100 pieces, these ND9 short-thread caps from manufacturer neolab - Labor fit standard short-thread autosampler vials used in GC and HPLC sample preparation. The blue PP body aids rapid colour coding and bench identification alongside the chemically clean PTFE septum for single-use injection protocols. Short-thread geometry supports consistent sealing without over-tightening, which suits routine high-throughput laboratory handling. Polypropylene durability combined with virgin PTFE makes the closure practical for everyday vial sealing where inert septum contact and straightforward needle penetration are needed.

Questions about neochrom® Schraubkappe Kurzgewinde ND9, PP blau mit Loch, PTFE virginal, 100 St.
What is this article?
neochrom® Schraubkappe Kurzgewinde ND9, PP blau mit Loch, PTFE virginal, 100 St. 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.
