The Microseal septum incorporates two separate sealing mechanisms; these sliding seals eliminate septum coring and the resulting accumulation of septum crumbs in the injection port liner.

• Eliminate septum coring
• Longer lifetime
• Consistent, low needle-insertion force
• 400 °C max injection port temperature

The Microseal septum uses a 23-gauge (0.63 mm, 0.025") needle or probe with a blunt, truncated conical tip. Since the syringe plunger end details are determined by manual or autosampler compatibility, often a removable needle syringe is an effective way to match both of these requirements. No adapter is required for the Agilent inlet. Installation is simple, requiring no modification of the injection port.
