A continuous-flow, variable mixing valve for perfusion experiments.
The device described here continuously mixes two solutions in any required ratio and has been used at flow rates of 6 ml/min in tissue perfusion experiments. Its low-cost construction consists of a three-way miniature solenoid valve driven by a simple electronic circuit. Mixing is stable, reproducible and accurate to +/- 1% of dial setting.
