sealing nut and 2 septa.
The Chromatography Research Supplies Endura-Seals kits are an alternative to typical silicone-rubber injection port septa for gas chromatography. The 2-part sealing system includes the septa and sealing nut, which is an ideal choice for automated analyses in the long sequences used with high capacity autosamplers.
The duckbill valve and wiper seal combination in the Endura-Seals is more resistant to needle wear and tear than traditional pierced septa. These septa allow the needle to glide through the valve to virtually eliminate coring. The seals utilize an elastomeric spring design instead of the metal spring used in some competing designs.
Kits are available in 11 mm and Shimadzu style kits. 11 mm Endura-Seals will fit in most instrument ports without the need for an adapter kit.
