Septa for Gas Chromatography
Product Code : JA-PLE-6452
Septa for Gas Chromatography (SKU JA-PLE-6452) are the silicone rubber discs that seal the injection port of a gas chromatograph while letting the syringe needle pass through at each injection. These silicone septa for gas chromatography are listed in a standard size of 3/8" diameter and 1/8" thickness, and other sizes are offered on request. JaincoLab supplies them to analytical, research and pharmaceutical analysis laboratories that keep replacement septa on hand for their GC injectors.

Applications of silicone septa for gas chromatography
A septum is the self-sealing barrier at the GC injector: it keeps the carrier gas inside the system while liquid or gas samples are injected through it with a syringe, and it is replaced during routine upkeep once repeated needle punctures start to wear it, so that the injector stays sealed.
- Sealing the injection port of packed-column and capillary gas chromatographs
- Allowing repeated syringe injections of liquid and gas samples
- Scheduled septum changes during instrument maintenance in QC and research laboratories
- Keeping spare septa for instrumental analysis work in pharmacy and chemistry departments
