Tips for Handling Septa
All septa, regardless of composition,
puncturability, or resistance to thermal
degradation will fail if they are mishandled.
Overtightening a septum nut invariably will
reduce septum lifetime by increasing coring/
splitting. All septa contain volatile materials
(e.g., phthalates) that are released when the
septum is heated (septum bleed). Because
most GCs are equipped with a septum purge,
septum bleed generally will disappear within
30 minutes after installing a new septum and
exposing it to normal injector temperatures.
All Restek septa are preconditioned and are
ready to use without delay.

Note: Due to differences in inlet design, the actual septum temperature for a given inlet setpoint can vary by
manufacturer. Restek recommends using only BTO® septa in Thermo TRACE and Focus GCs.
*For 17 mm inlets, the maximum temperature is 330 °C.
**12.7 mm and 17 mm septa packaged in precleaned glass jars.
