Glass Vials that meet these requirements are called EPA vials, or sometimes VOA vials (volatile organic analysis vials). SUNCITY sells EPA vials for environmental industry lab use. Flat bottomed EPA vials are available in 20 ml, 40 ml, and 60 ml sizes.
For many years, stream samples for analysis of volatile organic compounds have been collected without specific guidelines or a sampler designed to avoid analyte loss. In 1996, the U.S. Geological Survey's National Water-Quality Assessment Program began aggressively monitoring urban stream-water for volatile organic compounds.
