Description
CenterGuide AG3 Septa N 11,5 are gas chromatography septa engineered for dependable injector sealing in GC systems. These Advanced Green 3 septa feature an outer diameter of 11,5 mm and a thickness of 3 mm, with a maximum temperature of 400 °C for elevated injection-port conditions. Delivered in a blister pack containing 25 pieces, they facilitate orderly stock control and rapid replacement during instrument maintenance. The CenterGuide profile supports accurate needle guidance, which helps preserve seal quality and injection consistency on platforms specified for N 11,5 septa. Laboratories engaged in routine and method-development GC can rely on the clearly defined diameter and thickness for capillary or packed-column work that requires thermal stability. Available from manufacturer Macherey-Nagel, the Advanced Green 3 grade is oriented toward high-temperature chromatography where robust sealing performance is essential. Each blister pack presents the septa in a practical format for clean handling at the bench. Select this N 11,5 size when your injector configuration calls for an 11,5 mm outer diameter, 3 mm thickness and operation up to 400 °C in gas chromatographic practice.

Questions about CenterGuide AG3 Septa N 11.5
What is this article?
CenterGuide AG3 Septa N 11.5 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.
