Description
Closure caps for screw-thread vials in black with silicone/PTFE septa without slit, format N8, provide reliable sealing for N8 vials and ampoules in autosampler and sample-handling applications. The caps and septa are engineered for proper closure performance and are designed for comfortable use with needles. Silicone/PTFE construction supports consistent sealing behaviour in routine laboratory workflows. Each pack is supplied in tamper-evident, transparent polyethylene bags closed with a ziplock, so contents remain clearly visible and the bag can be resealed after opening. These closure caps from manufacturer ISOLAB Laborgeräte are intended for screw-thread vial systems where a non-slit septum is preferred. The black N8 format suits organised storage and ready access at the bench or autosampler. Supplied in a pack of 100 pieces, the closures offer a practical consumable option for laboratories working with N8 screw-thread vials that require dependable, resealable packaging and clear identification of remaining stock.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about cap + septa - N8 - silicone / PTFE - without slit
What is this article?
cap + septa - N8 - silicone / PTFE - without slit 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.
