DSR Digital RDE/RRDE Device
Can be used together with rotating disc electrodes (RDE), rotating ring disc electrodes (RRDE), and rotating cylindrical electrodes (RCE).
Background
In order to study the distribution of current density on the surface of electrodes, reduce or eliminate the influence of diffusion layers and other factors, electrochemical researchers have developed a high-speed rotating electrode through comparing various electrodes and stirring methods.
Since the working surface of this electrode looks like a disk, it is also called a rotating disk-ring electrode device.
Technology Advantages
Digital DSR | DSR was developed, along with the trend of digitization, on the basis of the new generation of digital information transmission technology.
|
The motor speed and direction are accurately controlled with high precision, fast response, strong signal processing ability, and anti-interference stability. | |
It is fundamentally different from imported instrument controlled by analog signal. | |
Digital reading is intuitively and accurately displayed. | |
It ensures finer speed tunning, better performance stability | |
Great workmanship and extraordinary quality | DSR works with silver graphite carbon brushes (silver content>80%), which ensures non-destructive transmission, good wear resistance and lubrication, and greatly improved stability. |
DSR works with a collimated rotating rod (15 mm diameter), which ensures stable dynamic reaction conditions. | |
DSR works with high-quality working electrodes manufactured in µm level. It ensures high collection efficiency and accurate calculation of electron transfer number. | |
DSR is powered by Direct Current, which ensures low energy consumption, strong stability, and greatly reduced clutter interference from the power grid. |
