Model 3325 Bi-Potentiostat for RRDE-3A and SEC2020

Model 3325 Bi-Potentiostat for RRDE-3A and SEC2020

Model 3325 Bi-Potentiostat
 
Very low-price and high-performance electrochemical analyzer

 

Model 3325 Bi-Potentiostat is a versatile electrochemical measurement device. The instrument incorporates a digital function generator, data sampling system, and potentiostat / bipotentiostat. The potential range is ± 5.0 V and the current range is ± 50 mA. It can measure currents greater than 100 pA. It is also possible to read the data measured with its predecessor, the Model 2325 Bipotentiostat.
The handheld size of the instrument allows it to be connected to a computer using a USB cable for communication and power supply. It is ideal for a field measurement and educational device in combination with a notebook PC.
It also has a remote function for the control of the RRDE-3A Rotating Ring Disk Electrode Apparatus and SEC2020 Spectrometer system.

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.

Spectrometer Control

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.
