The Princeton Applied Research model 636A Electrode Rotator is a high performance system providing rapid acceleration and excellent speed control. The model 636A may be connected to any of the Princeton Applied Research electrochemical instruments. It can be used as a simple rotating disk electrode or as a rotating ring-disk electrode. The outstanding specifications of the model 636 make it the ideal choice for any laboratory. The model 636A is suitable for use in hydrodynamically modulated systems. Its solid state controlled servosystem allows the electrode speed to follow an input signal with minimum distortion. This excellent performance is due to the use of a high speed, low inertia, permanent magnet DC motor and a high voltage, bipolar power supply. The rotational speed is adjustable to within 1% of the input setting 50-10,000 RPM. A voltage signal proportional to the rotational speed is available as an output. A variety of electrodes is available for the model 636A. The user can choose from Pt, Au, and glassy carbon for disk work. For custom electrode materials, please contact AMETEK for availability.
