Note: Due to differences in inlet design, the actual septum temperature for a given inlet set point can vary by manufacturer. Restek recommends using only BTO septa in older Thermo TRACE and Focus GCs. For Thermo TRACE 1300/1310 GCs, this recommendation does not apply; septa can be used to their maximum recommended temperature.
*For 17 mm inlets, the maximum temperature for BTO septa is 330 °C, 290 °C for Thermolite septa, and 300 °C for Thermolite Plus septa. For all injectors, minimum recommended operating temperature for BTO septa is 250 °C.
**12.7 mm and 17 mm septa packaged in precleaned glass jars.
