DEVEX (multi-layer) Gas Sampling Bags

       DEVEX gas sampling bag compared to Aluminium-plastic(multi-layer)gas sampling bag is higher performance replacement. DEVEX film is developed by Dalian HedeTechnologies Corporation specifically for making high quality gas samplingbags. It is composed of total 11 layer films(PET,PA,Aluminum,PE,etc) withthickness 120-140um.it has superb strength and low permeability; meanwhile it possesses excellent chemical inertness and stability. The overall property of DEVEX film exceeds that of PVDC film such as Saranâ.During lamination, environmental-friendly adhesive is used to eliminate solventresidue such as benzene, acetone, and esters. DEVEX gas sampling bags have awide range of applications including hydrocarbons, CO,CO2, nitrogen, hydrogen,oxygen, hydrogen sulfide, nitrogen oxides and halogens. But it is not recommended touse for the gas with high chemical,corrosivity and strong oxidizing propertysuch as: hydrogen sulfide, nitrogen oxides,strong basicity gas and halogens atlow ppb level. Compared to Polyfluoro film bags, DEVEX bags have low price, and can beused in VOCs assessment.
