  The septa uses only the highest quality materials to ensure proper function, and is especially suitable for gas chromatograph applications, ensuring that the septa will not fall into the sample vial during the sampling process. The septum is made of PTFE/silicone fusion, which has excellent inertness and can be used for multiple injections. The thickness is 1mm or 3mm, and PTFE is about 0.08mm. The crimp cap of vials is made of metal aluminum, which combines innovation with time-saving convenience, precise manufacturing tolerances, and a controllable manufacturing environment. The vial cap produced by this patented method truly combines the septum and the cap at the molecular level, which can avoid excessive evaporation and keep the sample vial properly sealed.
