Low Bleed High Temperature GC Septa
Low Bleed High Temperature Septa have a non-stick surface due to the plasma coating. They are designed for the lowest bleed possible at temperatures up to 400 °C, except 330 °C for the 17 mm septum. They are optimized for the most demanding GC and GC-MS applications where septa bleed could interfere with trace analysis. All septa except for the septa with diameters of 9.5 mm and 10 mm are available with a pre-pierced center depression which guides the needle to the same injection point, extending septa life and reducing needle bending.
These septa are formulated to extend the low-bleed and outstanding mechanical properties of premium GC septa to the highest-temperature applications. It retains remarkable softness and piercability at high temperatures, with extremely low bleed. Septa are 3mm thick, except Shimadzu-style plug septa, and are packaged in glass vials.
