Dissolved oxygen bottles are used to evaluate the health of water bodies by measuring the amount of dissolved oxygen present. Higher dissolved oxygen concentrations correlate with high productivity and little pollution. Made for on-site testing, these bottles are made from clear soda lime glass to easily see contents within. Available in a variety of millilitre volumes, the bottle is calibrated to its own stopper since stoppers and bottles are not interchangeable.
