Multi-Layer Foil Gas Sampling Bags

Sampling bags are a low-cost whole air sampling device for high level VOCs and permanent gases. Several EPA, NIOSH, and OSHA methods exist for bag sampling for a variety of applications: stationary sources emissions; workplace atmospheres; ambient, indoor air quality; and breath analysis. Choose the film type appropriate for your application. All our bags feature a polypropylene combo valve with hose connection to fit 3/16" ID tubing and syringe port with replaceable septum. A single eyelet provides handling convenience.

• Good stability for low molecular weight compounds, such as methane, CO, CO2, and permanent gases.
• Chemically inert with light and moisture protection.
• Not recommended for low ppm VOCs due to background levels.
• Protective 5-layer barrier minimizes gas permeability (60gauge nylon (outer layer), Metalized aluminum, Polyethylene, 0.0003" aluminum foil, 0.002" polyethylene (inner layer))
• Continous sampling temperature up to 190 °F (88 °C) indefinitely; do not exceed 190 °F for any period of time.
