Configuration for the experimental system
Model 3325 control terminal
Synchronize measurement and control of the external equipment such as SEC2020 Spectrometer system and RRDE-3A Rotating Ring Disk Electrode Apparatus can be performed using the CB-VS remote cable (15 pin).

Model 3325 Bi-Potentiostat software data processing
Model 3325 is digital controlled by PC software, whereas its price is almost same to the analog equipment. Dual channel CVs measured by Bi-Potentiostat can be plotted simultaneously on the software window. It is easy to overlay the CV curves for data comparison and the peak fitting function necessary for the data analysis is also included. In the setup screen, the rotation speed of the RRDE and gas purge ON/OFF can be controlled. The Model 3325 software is quite easy-to-use, even the beginners of the electrochemical measurements can easily work on it for the first time try.
Levich and Koutecky-Levich plot
Rotating disk electrode (RDE) is the method to obtain a forced convective voltammogram by which the data analysis is performed using the Levich or Koutecky-Levich plot, and also can calculate the parameters such as diffusion coefficient and electron number.
Rotating Disk Electrode Control
Rotation speed (rpm) and time of the rotating rdisk electrode can be controled by the software. Also, the quiet time and rotation state between and during the run can be selected.
When "Spectrometer Control" is executed with "On" selected, the TTL signal output is at a High level (5 V) during the measurement and at a Low level (0 V) during all other times. This command is used to control the spectrometer when performing spectroelectrochemical measurements. It works with CV, LSV, and i-t techniques.
Model 2323/2325 measurement data can be loaded and analyzed
Model 3325 software enables loading and analysis of data (.DY20) measured and saved by our previously sold models 2325. Comparison of data acquired with the Model 2325 and measured data with the Model 3325 can also be easily performed.
