AMERICAN Instrument's new potential controller for use with standard electrolysis equipment employs a d.c. generator for delivery of relatively high output currents and voltages. Called Redox-O-Trol, the unit is said to provide sufficient output for preparing selective reduction and oxidation products from organic compounds in substantial quantities. Unit controls either anode or cathode potentials within 100 mv. and can usually control with in less than 50 mv., says the company. Redox-O-Trol is a commercial version of an instrument recently designed by M. J. Allen of National Institutes of Health. Allen's unit is said to be able to provide high output currents and voltages. Through a monitor circuit based on a standard calomel electrode, Redox-O-Trol adjusts potential continuously as the electrolysis proceeds. Output voltage control is entirely through an electrical system. In use, the electrode potential is set at any desired value from 0.4 to 9 volts versus the reference cell. The calomel cell is ...
