The advantages of the Merlin Microseal septum include elimination of septum coring, longer life, and consistently 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. Because 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. Installation is simple, requiring no modification of the injection port.

Replacement Microseals for general-purpose (3 to 100 psi), low-pressure (1 to 45 psi), and SPME fiber (3 to 100 psi) applications are available. For use in SPME Arrow applications, a different nut/adaptor kit must be used; see Related Products.
