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

• Allow operation from 206,8 to 6894,7 mbar (general-purpose microseal septa) or 68,9 to 3102,6 mbar (low-pressure microseal septa)
• 400 °C maximum injection port temperature
