Septa
Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure synthetic red rubber septum that provides a reduced background level for specific GC applications, employing sensitive detectors such as ECD or NPD. PTFE/Silicone Septa (T/S) has high-quality, low background/blank value, 100% synthetic pure silicone septa.

Septa, Merlin Microseal™
Supplier: Restek
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.
