ALTEF gas sampling bags
Sampling bags are a low-cost, whole-air sampling device for high-level VOCs and per-
manent 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 ap-
plication. 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.
