The advantages of the Merlin Microseal Septum include elimination of septum coring, longer life, and consistent, low needle-insertion force. 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.
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.
