the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE/silicone septa Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is provided with a
PTFE/Silicone Septa: (T/S) High quality, pure silicone is laminated to 0.005” thick PTFE to give a pure, highly inert septum with excellent resealing characteristics even after repeated punctures. PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical.
make PTFE/silicone septa suitable for all types of chromatographic applications . A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent . PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical . Pre-slit PTFE
