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.
