Description
neochrom® screw closures in white polypropylene are open-top caps for ND24 systems with a 24-400 thread, intended for laboratory vials and bottles that require a centre access hole. Each cap features a 12,5 mm diameter opening so that a matching septum can be fitted for needle penetration during sampling or injection while the threaded shell secures the closure on the vessel. The caps are supplied without septa, allowing free choice of silicone/PTFE, butyl/PTFE or other ND24 septum grades according to method and temperature needs. White PP construction provides a clean, standard laboratory appearance and straightforward visual identification on the bench or in autosampler trays. Packs contain 100 pieces, suitable for method development, routine sample prep and restocking of ND24 open-top assemblies. These neochrom® screw caps from manufacturer neolab - Labor complete modular ND24 closure setups where separate purchase of caps and septa is preferred over pre-lined combinations.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about neochrom® Schraubverschlüsse, PP weiß, 12,5 mm Loch, Gewinde 24-400, 100 St./Pac
What is this article?
neochrom® Schraubverschlüsse, PP weiß, 12,5 mm Loch, Gewinde 24-400, 100 St./Pac 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.
