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.
