Rotation-rate control box

Figure 5.7 Pine electrode rotator and its associated rotation-rate control box. (http //www.pineinst.cotn/echetn/ imagebrowser.asp productlD=47123 imagelD=839).

The motor (or rotator) with a rotation rate control box is also commercially available, such as from Pine company as shown in Figure 5.7. This motor can precisely control the electrode s rotating rate normally from 100 to 4900 rpm. During the electrode rotating, the electrolyte solution wiU be sent to the electrode surface, and then thrown out from electrode surface, as shown in Figure 5.3(B).
