CS350M single-channel potentiostat/galvanostat

This is a comprehensive device integrating potentiostat, galvanostat, and frequency response analyzer. Equipped with a 24-bit high-precision AD converter, it delivers excellent stability, along with ultra-high resolution of up to 1mV (potential) and 1pA (current), making it ideal for precise electrochemical research.

Core advantages and unique features

Ultra high input impedance: The input impedance of the reference electrode is as high as 10 ¹² Ω, which almost does not draw current from the measured system, ensuring high stability and accuracy of the measured potential. This is crucial for experiments that require long-term stable testing.

Fast data acquisition: The AD converter supports 16 bit @ 1MHz high-speed acquisition, which can accurately capture transient changes in current and potential, making it very suitable for studying fast electrochemical reaction processes.

Flexible pulse technology: supports chronoamperometry (CA), chronopotentiometry (CC), and various pulse voltammetry methods (such as DPV, NPV), with a wide range of pulse width settings (0.0001 seconds to tens of thousands of seconds), providing powerful tools for complex electrochemical analysis.

Software and compatibility: Standard control software for Windows systems, typically providing a user-friendly graphical interface for setting up complex experiments, real-time monitoring data, and conducting post analysis.

Key Technical Highlights

High Precision and Wide Range: The voltage control range reaches ±10V (customizable to ±12V), while the current control range extends to ±2A. It features a broad current measurement range spanning 10 levels from 2nA to 2A, capable of detecting minute currents as low as 1pA.

High Output and Scanning Performance: With an output voltage of up to ±21V, it can drive high-impedance systems. During tests such as cyclic voltammetry (CV), the scanning rate can reach as high as 10,000 V/s, meeting the research requirements for fast kinetic processes.

Built-in electrochemical impedance spectroscopy function: The device features an integrated electrochemical impedance spectroscopy module with a frequency range spanning from 10 microhertz (μHz) to 1 megahertz (MHz), enabling impedance testing without the need for additional equipment.

Excellent scalability: With an external current booster, the maximum output current can be extended to 20A, 40A, or even 100A, catering to high-current testing scenarios (e.g., battery charge-discharge simulation).

Software Features

① Data analysis

Smooth, integrate, and differentiate the volt ampere curve, calculate the peak current, peak potential, and peak area of each oxidation-reduction peak, etc;

Three parameter or four parameter dynamic analysis of polarization curve, calculation of Tafel slope ba, bc, corrosion current density icorr, ultimate diffusion current, polarization resistance Rp, and corrosion rate, etc., can also be used to calculate power spectral density, noise resistance Rn, and spectral noise resistance Rsn (f) from electrochemical noise spectrum.

② Real time storage

CS Studio stores measurement data in real-time, and even if the test is interrupted due to power outage, the data before the interruption will be automatically saved.

③ Timed measurement

The CS Studio testing software has a timed measurement function. For some cases where the characteristics of the system changing over time need to be studied, the testing parameters and interval time can be set in advance, allowing the instrument to automatically measure at a timed time without human supervision, providing convenience for experiments.
