20mm Butyl Septa is used for 20mm Crimp Headspace Vial. Why use Butyl to make septa? This is because Crimp Headspace Vial is often used in gas chromatography. It is necessary to heat the sample to evaporate the gas and detect the gas. It is precisely because the gas needs to be stored inside the Via. The tightness requirements for Via are very high, while the silicone/PTFE septa is thinner and the tightness is not high enough. The 20mm Butyl Septa with a thickness of 3mm is the best choice for Crimp Headspace Vial.
