The Merlin Microseal is a long-life alternative to standard septum. The design of Merlin Microseal septa incorporates two separate sliding seal mechanisms. Since the needle or probe tip moves through the ring seals without puncturing them, no coring occurs, so the bleed and ghost peaks that can result from damaged septa are prevented.

(Available for US direct sales only. Customers outside the US—click here for alternate offer.)

Advantages of Microseal Septa

• Eliminate septum coring and associated contamination from septum crumbs in the inlet liner.
• Long lifetime due to innovative ring design and consistently low needle insertion force.
• Available for general purpose (3-100 psi) and low pressure (1 to 45 psi) operation.
• For use with 23 gauge (0.63 mm, 0.025″) needle or probe with blunt, truncated, conical tip.
