PTFE silicone septa is a new gasket which is used for chromatograph industry ,which is used for sealing sample vial . From the name PTFE silicone septa , you will easy know that it is bonded by PTFE and silicone rubber together ,we also have PTFE bonded Nitrile, Butyl,viton and other rubber material for other eara . But for medical and chromatograph industry . PTFE silicone septa is the best seal parts .
1) PTFE have a good physical properties.
high temperature resistance and low temperature resistance
‚corrosion resistant . It can resistant various medium. That is the biggest reason why chromatography vial used PTFE .
ƒPTFE is no harmful , also it won't affect the result when it used in chromatography vial.
2)Silicone rubber .
it is flexible and it is easy to seal the vial.
