Description
neochrom® screw caps ND13 with hole are black polypropylene open-top closures for laboratory vials that use a 13-425 thread. Supplied without septa, each cap provides a centre hole so users can fit a septum of their own choice to match method, solvent, or injection requirements. The black PP body gives a firm mechanical seal on compatible ND13 neck finishes while the open-top layout keeps the aperture free for needle access once a septum is installed. Pack size is 100 pieces per pack. These ND13 screw caps from manufacturer neolab - Labor are a flexible consumable option when laboratories prefer to stock bare open-hole closures and pair them with separate septa rather than pre-assembled combinations. Suitable for chromatography sample vials, storage vials, and general analytical workflows that standardise on the ND13 / 13-425 format. Choose and insert an appropriate septum before use, then tighten the cap onto matching ND13 glassware according to your laboratory procedure for secure closure and reliable sample handling.

Questions about neochrom® Schraubkappen ND13 mit Loch, PP schwarz, 100 St./Pack
What is this article?
neochrom® Schraubkappen ND13 mit Loch, PP schwarz, 100 St./Pack 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.
