A versatile automatic, recording potentiometric titrator was designed with a "thinking" velocity servomechanism to control the rate of titrant addition automatically and proportionately so that near-equilibrium conditions are maintained throughout the titration. Although designed for the remote titration of highly radioactive materials, it is equally useful for macro- and microtitrations of nonradioactive samples. By appropriate choices of the size of the syringe and of the concentration of the titrant solution, wide ranges of sample size can be titrated. In macrotitrations of uranium (about 0.2 meq. titrated with O.lN ferric suIfate) a relative standard deviation of 0.1% is obtained. In microtitrations of uranium or iron (about 2 mu eq. titrated with approximately 0.04N ceric sulfate) the relative standard deviation is 1.0%. (auth)
