Depth of Field: A Set-and-Forget Water Sampler

The OPEnSampler, created by OSU’s Openly Published Environmental Lab, autonomously collects and stores research-grade samples of water or wastewater in the field. 24 airtight containers have valves that seal as each one fills up, preventing contamination. And the whole thing fits inside an 80-quart cooler to keep samples cold for up to 10 days.

 
As with al OPEnS Lab innovations, the designs are freely available and customizable. To learn more, including how to build one of your own, visit open-sensing.org/opensampler.
