Silicone/PTFE is the most widely used material combination for septa used in vial closures (caps and seals). Verex Cert and Cert+ products are specially prepared from the highest quality raw
Septa for use with general chromatography vials, liquid injection 2-056 PTFE/Natural Red Rubber PTFE Natural Red Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR.
The silicone–PTFE septa are widely used because this material is temperature resistant (the maximum service temperature is 225°C) and soft and easy to puncture by needle even if tapered. In general, silicone septa display less off-gassing product ( 10 – 12 ).

Jan 26, 2022 · PTFE-Silicone Injector Septa, 11mm diameter, Pkg 12. 2021-2022 Chromatography Consumables & Supplies Catalog. Today's advanced and increasingly diverse laboratories are facing new challenges on a daily basis – starting from raw materials right up to the finished product.
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.
Septa are selected based on the chemical properties of the sample and the temperature to which the vial will be subjected during the analysis. PTFE/Silicone is for use with most organic solvents. PTFE/Silicone is not for use with chlorosilanes. It has good resealability and can withstand a temperature of 250°C.
