Rotating Cage Instruments

Rotating electrodes are the most widely used controlled-flow lab instruments. A Rotating Disc Electrode (RDE) is a simple tool where the working electrode current depends on the square root of the angular velocity. A Rotating Ring Disc Electrode (RRDE) is used for the quantitative and qualitative identification of species dissolving on the disc shaped working electrode. A Rotating Cylinder Electrode (RCE) provides a uniform shear stress on the cylindrical surface. A Rotating Cage (RC) is a specimen holder for rotating coupons – the weight-loss data is basically used for inhibitor selection.
