Septa (11 mm)
for Agilent 5880A/5890/6850/6890/7890 GCs with S/SL or PTV inlets
Enviromental analysis
These septa work great. Very durable and don't get cored easily. It's nice that they now come individually sealed.

Process and product quality control
I have used Restek as my preferred supplier for capillary columns and assorted consumables for my gas chromatography needs (Agilent) for almost 20 years! They are my preferred vendor for septa, inlet liners, inlet seals and fittings, ferrules, and columns (RTX fused silica).

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.
