Horizontal Van Dorn Sampler

Photograph of a Van Dorn sampler after it has brought up water from the Hillsborough River for testing. This device is open at both ends when lowered to the desired depth of water. The operator then drops a metal weight that travels down the line and releases the catch that snaps the ends closed. The bottle is then pulled back up and the water tested.
