When conducting environmental DNA surveys to determine what species are in the water, it is necessary to filter the water that contains DNA. Previously, expensive equipment and tools were needed to do this. We developed a system, powered by gravity, to filter the water using a rubber hose and a 3D printed adapter. With this inexpensive and compact tool, we can filter outdoors without electricity. It is hoped that this will enable more environmental DNA surveys to be undertaken. Detailed information is in the published scientific paper, and several scientists are now using this system for their research.
