Air Sampling Bag

Air Sampling Bags offer a convenient, reliable, economical way of collecting airborne chemical hazards. They are chemically inert, leak tested, mechanically strong, reusable, and non-contaminating. The Air Sampling Bags are available in ALTEF, Tedlar® and Multi-Layer Foil with a variety of fittings.  An explanation of each Air Sampling Bag follows:

• Tedlar® Bags have a very low gas permeation levels and high tensile strength. Bags resist puncture in the field. 2 mil Tedlar® film is an economical alternative to FEP bags. Tedlar® is much less permeable than FEP and is  unaffected by the chemical components of gases generally sampled, like carbon monoxide, sulfur dioxide, hydrogen sulfide, radon and mercaptans. Continuous use temperature from –98° to 400°F (temperature limit depends on fittings used). Required for many EPA testing methods. 

• ALTEF is a proprietary fluoropolymer film developed specially for the air sampling market. ALTEF has many of the desired characteristics of Tedlar® at a significantly lower cost. ALTEF is not recommended for ketones or esters in high concentrations (>30%) and is not suitable for storing H2S. Our Multi-Layer Foil bags are the best choice for collecting and storing H2S

• Multi-Layer Foil bags are ideal for sampling and storing H2S, and for low molecular weight compounds such as Methane, CO/CO2, Hydrogen, and inert gases which are not stable in Tedlar® or ALTEF.  Water and vapor proof, these flexible bags protect light sensitive compounds. Bags are available in standard capacities of 1, 3, 5, 10, 12, 25, and 40 liter capacities, with several fitting and valve options. They provide up to 5 day sample stability with minimal adsorption.
