Standard Septa

Part No.: 221-48972-91

Provides significant durability improvements compared to a conventional low-bleed septum, offering both low bleed and long life. The problem of sticking to the vaporizing chamber during continuous use at high temperatures experienced with a conventional septum has also been eliminated. Suitable for high-sensitivity analysis Maximum temperature (INJ setting temperature): 450°C

Part No.: 221-48398-91

Using this septum alleviates the problem of reduced durability when the vaporizing chamber is used continuously at 450°C. Compared to the LL septum, the increase in bleed when used at high temperatures is kept at a lower level. The problem of sticking to the vaporizing chamber during continuous use at high temperatures experienced with a conventional septum has also been eliminated. Suitable for high-sensitivity analysis at high temperatures Maximum temperature (INJ setting temperature): 450°C

Part No.: 221-76650-01

This septum is least influenced by a plasticizer. Better prevents septum coring. Low-bleed, suitable for high-sensitivity analysis Maximum temperature (INJ setting temperature): 340°C

Part No.: 221-75180

Low-bleed, suitable for high-sensitivity analysis at high temperatures Maximum temperature (INJ setting temperature): 350°C

Part No.: 227-35004-01

Useful for trace analysis and other applications where high sensitivity is critical Low bleed, highly robust (max. usable temp. 350°C)  High durability, proper sealing and good resistance to most chemical solvents.
