Can Tedlar® bags be reused?
It is possible to reuse Tedlar® bags for some applications. You should not reuse the bag after sampling compounds found at ppbv (parts per billion) concentrations, reactive compounds, or compounds that are known to adhere to the surface of the bag. Prior to reuse, the bags must be evacuated and thoroughly cleaned and flushed after each use with purified air or nitrogen. It’s recommended to perform an analysis of the final flush to ensure that the background levels present in the bag are acceptable for its intended use.
