The I-CHEM collects a full one-liter sample of first flush storm water within the first 30 minutes of a rain event in compliance with EPA sampling requirements. A floating ball valve seals off the sample collection port to prevent co-mingling with run-off water as well as volatile analyte loss. Water flows through the sampler’s collection funnel directly into a Nalgene® sample bottle so that no sample transfer is necessary before transport to the lab. After sampling is complete, remove the collection bottle from the reusable storm water sampler mounting kit’s tube (sold separately). Simply discard the bottle’s collection funnel and replace with a standard Nalgene closure for leakproof transport. To do future sampling, just insert a new I-CHEM storm water sampler in the tube. Because a new sample bottle is used each time, no decontamination is needed. The I-CHEM can be securely mounted in a storm water ditch, stream, or storm grate outfall using the storm water sampler mounting kit. Dimensions: Sampler, 13.2”H x 3.8” dia.; Mounting Kit, 15.6”H x 4.6” dia.
