Description
Aluminium crimp caps N-11 are laboratory closure components designed for secure sealing of compatible vials and sample containers. Each cap is fitted with a red PTFE-coated rubber sealing disc measuring 0,9 mm, combining chemical resistance at the sample interface with reliable elastomeric sealing performance. The open-hole design allows straightforward septum access for syringe sampling, injection, or headspace work without removing the crimped closure. Supplied in packs of 100 pieces, these aluminium Bördelkappen suit routine analytical, quality-control, and sample-storage workflows where consistent crimp geometry and clean septum contact are required. The N-11 cap size matches standard small-format crimp-neck vials commonly used in chromatography and general laboratory practice. Manufactured by Witeg, the aluminium shell provides a durable, form-stable crimp that holds the PTFE-faced rubber disc firmly in place after sealing. Net weight per pack is 0,032 kg. Use with appropriate crimping tools matched to N-11 geometry to achieve a uniform seal. Ideal for laboratories standardising on aluminium crimp closures with PTFE-coated rubber septa for everyday sample handling and instrumental analysis.

Questions about Aluminum crimp caps
What is this article?
Aluminum crimp caps is the article on this page. Luminix Health distributes Witeg 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.
