An automatic animal watering system has a manifold for transporting drinking water, a controlled volume dispenser in the manifold for receiving a volume of drinking water, an inlet valve, and an outlet valve. Hyperpolarized xenon-129 is introduced into two compartments between which xenon-129 can be exchanged, for example, into the blood vessels of mammal organs and the tissue of said organ or into compartments within inorganic objects. The connector holders are provided at a connector storage location. Certain embodiments of the invention can also be used to maximize the production of activated neutral atoms and molecules from the de-activation apparatus.
