Overview
The Princeton Applied Research model 636A Electrode Rotator is a high performance system giving you 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 your 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 to 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 the factory for availability.
While many users are interested in the behavior of a species in solution at an inert electrode, the corrosion scientist is concerned about the behavior of many different active electrodes. The needs of this group have been answered by the use of our Quick-Change electrodes assemblies. An investigator can choose a disk geometry or a cylinder geometry and have the electrode machined out of the metal of interest. The rotator is designed to accept different arbors to accommodate these two options. For corrosion studies a special disk assembly that allows the user to insert the disk of their choice is available.
