An improved saturation apparatus for continuously generating large volumes of water solutions of hydrophobic compounds for conducting aquatic bioassays is described. Closed 19 L stainless steel soda carbonation vessels replace the open glass vessels commonly used. The apparatus has been used successfully with liquid, semi-liquid and solid compounds and has delivered up to 200 ml/min of toxicant ladened water to a test system. The modular design of this saturator makes the flow capacity almost infinite by simply connecting another vessel in line.
