- Excellent alternative to Tedlar bags for collection of most VOCs
- Unlike Tedlar bags, ALTEF bags do not produce background levels of dimethylacetamide (DMAC) or phenol.
- Very low VOC and sulfur background compared to Tedlar bags.
- Not recommended for ketones, acetates, hydrogen sulfide, or permanent gases.
- Durable polyvinylidene fluoride (PVDF) film is resistant to abrasion and chemicals, including most acids and organic compounds.
- Contain no additives, fillers, or pigments.
Note: Use only Point Style 5 or H syringe needles.

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 ALTEF 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.
