Additional Product Details

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.
