Septa for Agilent Instruments

Septa for Agilent Instruments

Septa are available for a variety of different applications and have different upper temperature limits. Lower temperature septa are usually softer, seal better, and can withstand more punctures (injections) than their high-temperature counterparts. If septa are used above their recommended temperatures, they can leak or decompose, causing sample loss, lower column flow, decreased column life, and ghosting.

Agilent premium non-stick inlet septa are designed and manufactured to provide a reliable non contaminating seal. The tri-fold blister pack ensures that each septum remains clean and ready to use.

  • Proprietary plasma treatment prevents sticking and unnecessary inlet cleaning
  • Innovative blister packaging keeps each septum clean and ready for use
  • Center point guides the needle for easy penetration, less coring and longer life
  • Precision molding assures accurate fit in the inlet
  • Each batch is tested for bleed on Agilent 7890 GC-FID
  • Premium formulations selected for sealing and chromatographic cleanliness
  • No need to bake septa before using

There are three types of Agilent premium septa from which to choose to suit all GC application types:

  • Bleed and Temperature Optimized (BTO) - Suitable up to 400°C and recommended for trace analysis
  • Advanced Green - Recommended up to 350°C and good general purpose septum
  • Long Life - Recommended for use with injection port temperatures below 350°C

Agilent's general purpose septa are made from an enhanced injection-molded silicone rubber. The septa material, gray in color, is specified to withstand over 200 automatic injections at an injection port temperature of 350 °C.
