CALI-5-BOND™ LIQUID, AIR AND GAS SAMPLING BAGSTechnically superior, custom made, and re-usable... Liquid, air and gas sampling bags and related accessories for all testing requirements. From Outer Space to the depths of the sea. Our Cali-5-Bond™ sampling bags are multi-layer foil bags made to order with standard and custom sizing and valve options to fit your specifications based on application and testing requirements. They provide moisture and light protection and are the only gas sample bags suitable for low molecular weight compounds such as methane, CO, CO2 , and hydrogen sulfide. Also suitable for permanent gases such as hydrogen and oxygen. Unlike our Cali-5-Bond™ bags, these compounds can become unstable when collected into standard Tedlar® bags*. Cali-5-Bond™ foil gas sampling bags are frequently used to store and transport calibration gases and gas standards. Gas sampling bags are exclusively used for several EPA, NIOSH, and OSHA methods.
