Abstract
A self-filling graduated cylinder system for efficiently filling a graduated cylinder with a chemical solution. The self-filling graduated cylinder system generally includes a graduated cylinder having an interior, an upper end, an upper opening in the upper end a lower end opposite of the upper end, and a check valve attached to the graduated cylinder near the lower end of the graduated cylinder. The check valve is adapted to allow a liquid chemical to flow upwardly through the check valve into the graduated cylinder and to prevent the liquid chemical within the interior of the graduated cylinder from flowing downwardly through the check valve.
