Description
CenterGuide AG3 Septa N 9 are gas chromatography septa intended for reliable injector sealing in GC workflows. These Advanced Green 3 septa have an outer diameter of 9 mm and a thickness of 3 mm, with a maximum temperature rating of 400 °C for demanding thermal conditions at the injection port. Packed as 25 pieces in a blister pack, they support routine sample introduction where consistent needle guidance and a stable seal help limit leakage and septum-related artefacts. The CenterGuide geometry assists precise needle entry, which is useful for reproducible manual or autosampler injections on systems configured for N 9 septa. Analytical laboratories running capillary or packed-column GC methods can use these septa in everyday methods that require defined dimensions and elevated temperature capability. Offered by manufacturer Macherey-Nagel, the Advanced Green 3 type suits high-temperature GC practice where durable sealing and controlled background behaviour matter. Each blister unit keeps the septa organised for quick change-over during maintenance or method setup. Select this N 9 format when your injector specification calls for a 9 mm outer diameter, 3 mm thickness and operation up to 400 °C.

Questions about CenterGuide AG3 Septa N 9
What is this article?
CenterGuide AG3 Septa N 9 is the article on this page. Luminix Health distributes Macherey-Nagel 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.
