Description

Suitable to overcome the degradation of the septa, due to prolonged high temperatures which occurs in silicone rubber septa

  • Septa degradation results in baseline drift and additional peaks
  • When the PTFE is faced towards the column packing this issue is eliminated
  • Designed for applications where greater inertness is required
  • The off-white silicone rubber body (123 mil) provides plenty of support for the yellow PTFE-face (2 mil)
  • After the PTFE is ruptured during injection, some bleeding may occur
  • It is recommend to use a needle guide to minimize the size of the punctured area
  • For use with 200°C to 300 °C inlet temperatures
