Description
neochrom® aluminium crimp caps ND11 with hole and virgin PTFE septum are precision closures for laboratory sample vials. These colourless lacquered aluminium crimp seals incorporate a 5,5 mm centre hole and a virgin PTFE septum 0,25 mm thick. The high-temperature-resistant septum design is intended for single-injection workflows where chemical inertness and a reliable seal are required.
This article is part of Screw caps & closures, in Stoppers, caps & closures.
Packaged as 100 pieces per pack, the ND11 format matches standard 11 mm crimp-neck vials used in GC and HPLC sample preparation. The virgin PTFE septum forms a clean, chemically resistant barrier suited to demanding analytical work. These crimp caps from manufacturer neolab – Labor under the neochrom® range combine durable aluminium shells with carefully selected septum material for consistent laboratory sealing.
The colourless lacquer finish gives a neat appearance, while the defined hole diameter supports straightforward needle access during injection. High-temperature resistance of the PTFE virgin septum helps maintain seal integrity in elevated-temperature methods for single-use injection sequences. Laboratories that need dependable ND11 aluminium crimp closures will find this pack a practical everyday consumable for routine analytical sealing tasks.

Questions about neochrom® Alu-crimp capn ND11 with Loch, Septum PTFE virginal, 100 pieces/Pack
What is this article?
neochrom® Alu-crimp capn ND11 with Loch, Septum PTFE virginal, 100 pieces/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 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.
