Premium Non-Stick BTO Septa, 5 mm w/CenterGuide, 50-pk.

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, 1600/1610 GCs, this recommendation does not apply; septa can be used to their maximum recommended temperature.

*For all injectors, minimum recommended operating temperature for BTO septa is 250 °C.
