CRS Endura-Seal GC septa are resilient to needle wear and tear, eliminates coring and are recommended for automated analysis that requires long run times. Endura-Seals are a patented alternative to typical silicone-rubber injection port septa for gas chromatography. They work in a 2-part sealing system that includes the septa and the sealing nut. Endura-Seals offer excellent durability and good resealing, for use at maximum injector temperature of 400°C.
