"These are the only septa we use in the entire lab across all departments. By far the industry standard, very wide range of optimal temperature uses. Almost never any septum bleed issues"

Septa consumable works great.
Application Area:Gas Chromatography
"Doesn't show carryover, used daily for Agilent GC-MS/MS. Fits well and does exactly what it is supposed to do."
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 Thermolite septa is 290 °C.
**12.7 mm and 17 mm septa packaged in precleaned glass jars.
