The next generation open-source, 3D-printable Niskin bottle has arrived!

Oceanography for Everyone, Science

The Niskin bottle, a seemingly simple device designed to take water samples at discrete depths, is one of the most important tools of oceanography. These precision instruments allow us to bring ocean water back to the surface to study its chemical composition, quality, and biologic constituency. If you want to know how much plastic is circulating in the deep sea, you need a Niskin bottle. If you need to measure chemical-rich plumes in minute detail, you need a Niskin bottle. If you want to use environmental DNA analyses to identify the organisms living in a region of the big blue sea, you need a Niskin bottle.
