Bi-potentiostat / Bi-galvanostat Electrochemical Workstation
SKU: SC2000
Bi-potentiostat / Bi-galvanostat Electrochemical Workstation
MSE Supplies offers electrochemical workstation (bi-potentiostat / bi-galvanostat) with built-in EIS model. It has two sets of built-in independent potentiostat /galvanosta. Each set provides full electrochemical techniques (EIS included). Experiments can be conducted simultaneously in each channel. Additionally, the two channels can jointly complete experiment of two-working electrode system (RRDE and hydrogen diffusion). With high performance in stability and accuracy with advanced hardware and well-functioned software, it is a comprehensive research platform for corrosion, batteries, electrochemical analysis, sensor, life science and environmental chemistry etc.
Applications:
(1) Electrosynthesis, electrodeposition (electroplating), anodic oxidation, electrolysis
(2) Oxygen reduction reaction(ORR), oxygen evolution reaction (OER), hydrogen evolution reaction(HER), carbon dioxide reduction
(3) Energy and materials (Li-ion battery, solar cell, fuel cell, supercapacitor), advanced function materials, and sensor
(4) Corrosion behavior of metals, and anti-corrosion evaluation
(5) Fast evaluation of inhibitor, water quality stabilizer, coating, cathodic protection efficiency
