Gas Bags

Gas Sampling Bags

These gas sampling bags offer convenient, reliable, economical way of collecting airborne chemical hazards. They are chemically inert, leak tested, mechanically strong, reusable, and non-contaminating. Tedlar®, Charcoal Tedlar®, FEP, PFA and other materials, with a variety of standard and custom fittings as well as These gas sampling bags offer a Gas Sampling Bags are available in ALTEF, optional metal eyelets for easy holding and storage.  

Tedlar® Gas Sampling Bags

Velocity Gas Sampling BagsTedlar® film has 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.

 FEP Gas Sampling Bags

Velocity Gas Sampling BagsFEP is one of the most chemically inert materials for making gas sampling bags. It works well in extreme temperatures ranging from –400° to 400°F; allowing it to be used in most stack sampling conditions. 5 mil FEP film is completely resistant to the most severe corrosives. Relatively low permeability results in minimal sample loss. FEP bags can be specified for applications involving rough handling.

 Multi-Layer Foil Gas Sampling Bags

Velocity Multi-Layer Foil Gas Sampling BagMulti-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®, ALTEF, or FEP. Water and vapor proof, these flexible bags protect light sensitive compounds. Bags are available in standard capacities of 1, 2, 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.

ALTEF Gas Sampling Bags

Velocity ALTEF Gas Sampling BagALTEF 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.
