Description
Closure caps for N20 crimp-neck vials in silver finish with silicone/PTFE septa without slit are intended to support reliable sealing and consistent system performance in analytical and sample-handling workflows. The caps are designed for smooth needle penetration and are engineered for a proper seal on standard N20 roll-rim vials. Packaging is in tamper-evident, transparent ziplock bags that allow quick visual identification of contents and can be resealed tightly after opening, helping maintain order at the bench. Supplied in packs of 100 pieces, these closures suit routine chromatography, sample storage and general laboratory use where a non-slit silicone/PTFE septum is preferred. The combination of a silver crimp cap and dual-layer septum is a common choice for laboratories seeking reproducible closure behaviour with N20 vials. Manufactured by ISOLAB Laborgeräte, the caps fit established crimp-neck vial systems and support everyday sample preparation and analysis routines without unnecessary complexity.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about cap + septa - silicone / PTFE - without slit - for N20 vials
What is this article?
cap + septa - silicone / PTFE - without slit - for N20 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.
