Abstract: A mixer-sparger assembly includes a first body portion; a second body portion; a gasket positioned between the first and second body portions to form a seal between the two body portions; an inlet disposed in the first body portion; a flexible tube connected to the inlet; a fluid chamber disposed in the first body portion or the second body portion and in fluidic communication with the inlet; an outlet disposed in the first body portion or the second body portion and in fluidic communication with the fluid chamber; and a plurality of supports extending downwardly from the second body portion to form a self-standing assembly with a space disposed below the second body portion. The first and second body portions have a density greater than about 1.0 g/cm3, and the inlet, fluid chamber, and outlet in spatial combination are configured to have an axis of rotational symmetry.
