Description
White screw caps for sample bottles N24 with silicone/PTFE septum and slit are designed for laboratory sample vials where needle access and a dependable seal are both required. The slit septum supports smooth needle penetration in autosampler and related workflows, while the overall cap geometry is configured for proper sealing and consistent system performance. White N24 screw caps with a silicone/PTFE liner combine elastic sealing behaviour with a chemically resistant contact layer, making them suitable for routine sample preparation, injection and short-term storage on the bench. Available in packs of 100 pieces from manufacturer ISOLAB Laborgeräte, they are supplied in tamper-evident, transparent bags closed with a ziplock. The clear bag allows rapid visual identification of the product, and the ziplock enables the pack to be resealed after use so unused caps remain protected and organised. These white N24 silicone/PTFE screw caps with slit are a practical choice for laboratories that need needle-friendly closures, reliable sealing of sample bottles and convenient, resealable packaging for daily analytical work.

Questions about cap + septa - silicone / PTFE - with hole - for N24 vials
What is this article?
cap + septa - silicone / PTFE - with hole - for N24 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.
