Multi-Layer Foil Gas Sampling Bags - Locking Combo Valve
- 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 4-layer barrier minimizes gas permeability. 60 gauge nylon (outer layer), Polyethylene, 0.0003" aluminum foil, 0.002" polyethylene (inner layer)
- Maximum operating temperature: 82 °C (180 °F).
Sampling bags are low-cost, whole-air sampling devices for 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. All our multi-layer foil 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.
