Multi Layer Foil Gas Sampling Bags

Description

Multi-layer foil bags are low-cost air sampling bags featuring four protective layers of nylon, aluminum foil, and polyethylene. Often called aluminum-foil bags, they offer reliable stability for lower molecular weight gases. They serve as an excellent alternative to canisters for checking indoor and outdoor air quality under government norms. These bags effectively measure pollution from ppb to ppm levels to help control air quality.
