General description

The Merlin Microseal System is a septum-less system that provides very long life. Because there is not a septum to pierce, septum fragments will not be formed and deposited in the inlet liner. The septum contains a series of seals (wiper rib, o-rings, and a duckbill valve) that allow a needle to enter while maintaining a leak-free seal. The septum can be used only with a syringe that has a 23 gauge "blunt tipped" needle, or with an SPME fiber assembly with a 23 gauge needle. The thicker shaft is required to make the necessary contact with the septum seals.

Other Notes

Three septa versions are available:
  • Low Pressure for use with 23 gauge syringe needles, and injection port pressures between 1 and 45 psi. Do not use with syringe needles that have beveled tips.
  • General Purpose for use with 23 gauge syringe needles, and injection port pressures between 3 and 100 psi. Do not use with syringe needles that have beveled tips.
  • SPME for use with 23 gauge SPME fiber assemblies. Do not use with SPME fiber assemblies that have beveled tips.

Note: Do not use with beveled tips.
