Injection Port Septa

Injector septa used in Gas Chromatography provide a critical role in maintaining system isolation but allowing the sample to be introduced onto the column in a Quantative manor. Since the injector septa provide the seal between the inner workings of the injector and the laboratory environment, it must have several desirable
characteristics. For best performance the septa should be inert, low off-gassing of silicone oligomers, soft enough to avoid bending the needle and reseal after injection and resistant to coring by the syringe.

We offer a range of inert septa, suited to different application needs.

  • The BTO (orange) septa offer the ultimate in inertness and are ideally suited to GC/MS applications and trace analysis.
  • The mid-range advanced green septa combine low inlet adhesion properties with long lifetime and are recommended for GC applications.
  • The blue septa offer a high-performance cost-effective alternative, offering a good level of inertness and are also recommended for GC applications.

Septa come packed in a glass jar, for high purity. Or select the disc format where septa are located in individual pockets for ease of selection and avoids any risk of cross contamination.
