Foil Gas Sampling Bag, 25 L, 18" x 24", CHROMSPEC, with Screw Cap Combo Valve with Septum

Multi-Layer Foil Gas Sampling Bags

Our Multi-Layer Foil Gas Sampling Bags are the best choice for collecting and storing H2S. Ideal for sampling and storing for low molecular weight compounds such as Methane, CO, CO2, Hydrogen, and inert gases which are not stable in Tedlar®, ALTEF, or FEP. Water and vapor proof, these opaque, flexible bags protect light sensitive compounds. They provide up to 5 day sample stability for many VOC's, with minimal adsorption. Opaqueness protects samples from ultraviolet light. Foil layers provide very low permeability and complete moisture barrier

Maximum operating temperature: 190 °F
