This patented system provides closed loop sampling that virtually eliminates sample spillage, employee exposure and environmental release of product. Once the sample has been taken it can easily be returned to the process and a new sample taken in one step, which eliminates the sample’s disposal into sewers and subsequent environmental issues. Once the sample has been collected it can be easily transported to the lab for analysis i.e. chromatograph, mass spectrometer or any other type of lab analyzer. Drushel Design and Development can modify the Enviroflow Sampling System to fit most sampling situations.
