Description
Closure caps for screw-thread vials in blue with silicone/PTFE septa with slit (N9) are intended for autosampler sample vials where controlled needle access and reliable sealing are required. The pre-slit septum eases needle entry while the silicone/PTFE construction supports a stable seal against evaporation and sample loss during chromatographic analysis. These closures are developed for good needle compatibility and consistent system performance with matching N9 screw-thread vials in HPLC, GC and related sample preparation. Available in packs of 100 pieces from manufacturer ISOLAB Laborgeräte, they are packed in tamper-evident, transparent ziplock bags for clear identification and practical laboratory handling. Blue colour coding aids quick selection among different septum styles on the workbench. Non-sterile consumables for routine analytical use, they suit laboratories that need repeatable fit, straightforward piercing behaviour and organised storage of vial closures for everyday autosampler workflows.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about cap + septa - silicone / PTFE - with slit - for N9 vials
What is this article?
cap + septa - silicone / PTFE - with slit - for N9 vials is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
