Pyrosep S-1 Septa diam. 6 mm ( 1/4 in.). GC Inlet Temperature: 300 °C to 400 °C. Pyrosep S-1 septa are made from a PTFE-type elastomer conditioned at 300 °C to minimize bleed. Because they are relatively hard, they must be used with a needle guide (to prevent the needle from buckling) and only at high temperatures. Our adapter rings offer substantial savings by enabling you to use smaller septa.

Pyrosep™ S-1 Septa diam. 9.5 mm ( 3/8 in.). GC Inlet Temperature: 300 °C to 400 °C. Pyrosep S-1 septa are made from a PTFE-type elastomer conditioned at 300 °C to minimize bleed. Because they are relatively hard, they must be used with a needle guide (to prevent the needle from buckling) and only at high temperatures. Our adapter rings offer substantial savings by enabling you to use smaller septa.
