SUMMARY1 A simple water sampler and an incubation chamber are presented. The water sampler is simpler in construction than the Ruttner sampler and other comparable devices. In addition to enclosure of water at a discrete depth, the incubation chamber releases a radioisotope or other substance of experimental interest into the sample. 2 Tests of performance are presented, demonstrating efficiency in enclosure of water from discrete depths, and time course of mixing of a tracer into the sample after activation of the release mechanism.
