Description
Closure caps for crimp-neck vials N11 in silver with silicone/PTFE septum without slit are designed for reliable sealing of roll-rim sample vials in analytical workflows. These caps deliver consistent system performance and are engineered for smooth needle penetration during sampling or injection steps. Each unit is specifically configured to ensure a proper, leak-resistant seal on N11 crimp-neck vials commonly used in chromatography and sample storage. Supplied in packs of 100 pieces from manufacturer ISOLAB Laborgeräte, the closures arrive in tamper-evident transparent bags closed with a ziplock. The clear packaging allows quick visual identification of contents, while the resealable ziplock keeps remaining caps protected and organised after opening. Ideal for laboratories requiring dependable septum integrity without a pre-cut slit, these silver aluminium-style crimp caps with silicone/PTFE liners support routine sample handling, autosampler use and general laboratory vial sealing applications where chemical resistance and needle compatibility matter.

Questions about cap + septa - silicone / PTFE - without slit - for N11 crimp vials
What is this article?
cap + septa - silicone / PTFE - without slit - for N11 crimp vials is the article on this page. Luminix Health distributes ISOLAB 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.
