Molded GC Septa

Injection port septa used in gas chromatographic analyses should exhibit low bleed, resist leaks, and be easy to penetrate. For years, Thermogreen® LB-2 septa have been considered by many as the benchmark GC septa for these parameters due to several performance advantages over other commercially available septa. A new generation septum, molded Thermogreen LB-2, continues the Supelco tradition of setting the benchmark in high performance.

The strict tolerances resulting from the constant dimensions of the mold itself result in septa that are easier to install and consistently fit better. Using a rubber formulation exclusive to Supelco, molded Thermogreen LB-2 septa exhibit an ultra low bleed profile, are very resistant to both slivering and coring, and have a high puncture tolerance when used in autosampler applications.
