Product Introduction
BiPotentiostat/BiGalvanostat with built-in EIS model CS2350M has two sets of built-in independent potentiostat /galvanostat. So it equals that you have 2 sets potentiostat/galvanostat in one instrument. Each set provides full electrochemical techniques including EIS. Experiments can be conducted simultaneously in each channel. Besides this, the two channels can jointly complete experiment of two-working electrode system such as RRDE and Hydrogen diffusion. CS2350M bipotentiostat is the real double-channel potentiostat. It uses Ethernet connection. EIS module is included in each channel. CS2350M EIS bipotentiostat is an affordable instrument. With the same level and function product, our price is just half or one third of some other brands.

Typical applications
Rotating ring-disk electrode (RRDE)
Oxidation/reduction reaction (ORR) study: while measuring the polarization curve of disk electrode in the main channel, apply a constant polarization potential on the ring electrode, and thus detect the intermediate products on the disk electrode. RRDE test becomes the typical method for ORR study. CS2350M can be connected to any RRDE equipment.

Technical advantages
1. Impedance (EIS)
Corrtest potentiostat applies correlation integral algorithm and dual-channel over-sampling technique, and has strong anti-interference ability. It is suitable for EIS measurements of high-impedance system (>109Ω, such as coating, concrete etc.).

2. Polarization curve
Tafel plot can be obtained. The user can set the anodic reversal current (passivation film breakdown current) of the cyclic polarization curve to obtain material’s pitting potential and protection potential and uate the its susceptibility to intergranular corrosion. The software uses non-linear fitting to analyze polarization curve, and can make fast evaluation of material’s anti-corrosion ability and inhibitors.

During EIS data analysis, there is built-in fitting function to draw the custom equivalent circuit.
Real time saving of data: The data can be automatically saved even in case of sudden power off.
Combination test: it can facilitate the automation of experiments and save time. With the unique function of combination test, you can choose several techniques, and set the wait time, the start time, and the cycles. Choose the experiments you want to run. Then you can make auto measurement of the set experiments as you want without having to wait in the lab. This function is especially useful if you have multi experiments to run and save your time greatly.
Data open: You can open the data files by txt format in notepad. Data can also be opened in Origin
