Description
neochrom® Screw Cap Short Thread ND9 is a red polypropylene screw closure with short thread 9-425 and a 6 mm centre hole for laboratory vials. It is equipped with a virgin PTFE septum of 0,2 mm thickness that is high-temperature resistant and designed for single-injection use. The open-hole configuration supports reliable needle penetration in chromatographic sampling and related analytical workflows, while the thin virgin PTFE layer provides an inert contact surface at the sample headspace. Packaged as 100 pieces, these ND9 caps from manufacturer neolab - Labor are compatible with common short-thread autosampler vials used in GC and HPLC sample preparation. The red PP body enables clear visual coding on the bench and works with the virgin PTFE septum for clean single-use injection protocols. Short-thread geometry promotes consistent sealing without excessive torque, supporting efficient high-throughput laboratory handling. This polypropylene and virgin PTFE combination is suited to routine vial sealing where chemical inertness of the septum face and straightforward needle access are required.

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