Modulated Speed Rotator (MSR) and Rotating Disk Electrodes (RDE's)
Pine Research Instrumentation

DSCN0705An RDE is a working electrode used in a three-electrode system. The conductive disk of the electrode is made of a noble metal or glassy carbon; however, other conductive material can also be used based on specific needs.  The MSR is used with RDE’s. The apparatus can be assembled and taken apart, and the rotation rate is controlled externally. Electrode connections are made to the rotating shaft using silver-carbon brushes to avoid problems of handling traditional mercury contacts.  Compared with still and unstirred experiments, where the steady-state current is limited by the diffusion of substrate, the rotation of the electrodes can quickly achieve conditions in which the steady-state current is controlled by the solution flow.

  • MSR rotator has capability to modulate rotation rate and works in conjunction with rotating disk electrodes
  • Multiple RDE tips can be used in the same shaft
  • Special design of the E4TQ Series Change Disk RDE allows same RDE tip to be used repeatedly with different disk samples
