Description
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. Physical Specifications Composition: proprietary polyvinylidene fluoride (PVDF) film Thickness: 0.003" Tensile Strength: 6100 psi Max. Operating Temp.: 82 °C (180 °F) Specific Gravity: 1.78 g/mL Oxygen Permeability: 58 cc/m 2 /day Water Vapor Permeability: 12-15 g/m 2 /day Carbon Dioxide Permeability: 172 cc/m 2 /day
Features & Benefits
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.
