A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.
Figure 3 - Typical mass chromatogram of volatile residue in hexane caused by PTFE/silicone septa: a) hexane extract of a piece of septum; b) vial septum was punctured once by a syringe to sample 1 μL hexane for GC analysis; c) hexane in the last vial was reanalyzed after 3 days; and d) analyzed immediately after 100 μL hexane was added from one vial to another (the septum was punctured 10
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.
A layer of PTFE on each side of medium hardness silicone. Most resistant to coring with above average resealing characteristics. Recommended for most demanding applications such as trace analysis, longer time between injections, or for internal standards. Use with any autosampler using large diameter, blunt-tip syringe needles.
