Description
neochrom® screw cap ND9 short thread is a black polypropylene closure for ND9 short-thread sample vials used in analytical laboratories. It features short thread 9-425, a 6 mm centre hole, and a silicone white/PTFE red septum with 1,0 mm thickness. The assembly withstands temperatures from −60 °C to +200 °C and is intended for single-injection applications. Available in packs of 100 pieces from manufacturer neolab - Labor, the black PP housing helps distinguish vial sets on crowded benches while the open hole permits direct needle access through the septum. This neochrom® ND9 black screw cap suits chromatography and general sample-handling setups that standardise on 9-425 short-thread vials and prefer disposable closures for single-injection protocols. The silicone/PTFE laminate provides the sealing face for routine vial work, and the defined 6 mm aperture supports consistent syringe entry. Choose this colour variant when black polypropylene caps with white silicone and red PTFE are required for organised ND9 short-thread workflows.

Questions about neochrom® Schraubkappe ND9 Kurzgewinde, PP schwarz mit Loch, Silikon weiß/PTFE r
What is this article?
neochrom® Schraubkappe ND9 Kurzgewinde, PP schwarz mit Loch, Silikon weiß/PTFE r 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.
