Description
17 mm high-performance GC septum (ultra pure), red, is a durable, universal consumable for gas chromatography injection ports. These septa are specified for a long service life of at least 450 injections and remain suitable for inlet temperatures up to 400 °C, supporting demanding analytical sequences. An integrated Center Guide improves needle guidance during injection, helping maintain consistent penetration and reducing handling issues at the inlet. Low bleeding behaviour limits outgassing of siloxanes, which supports cleaner baselines and more reliable chromatographic performance. Excellent removability from the injection port simplifies septum exchange during routine instrument maintenance. Supplied as a red ultra-pure grade in a pack of 25 pieces, the format suits regular restocking of GC systems in method development, routine analysis and quality-control laboratories. These GC septa from manufacturer Altmann Analytik combine thermal stability, low bleed and practical needle guidance for everyday capillary and packed-column workflows. The 17 mm diameter matches common inlet geometries, while the 25-piece pack keeps spare septa ready beside the instrument without excess inventory.

Questions about 17 mm High performance GC Septum (Ultra pure), red, 25 pc/PAK
What is this article?
17 mm High performance GC Septum (Ultra pure), red, 25 pc/PAK is the article on this page. Luminix Health distributes Altmann Analytik 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.
