Corrtest Single-Channel Potentiostat/Galvanostat with EIS Function

Single-Channel Potentiostat/Galvanostat with EIS Function

Franklab offers a high-performance Single-Channel Potentiostat/Galvanostat with EIS capability. The system integrates a DDS arbitrary function generator, potentiostat / galvanostat, and a frequency response analyzer (FRA). Equipped with dual 24-bit Delta-Sigma A/D converters, it delivers exceptional stability along with high-resolution measurements—down to 1 µV for potential and 1 pA for current.

Featuring over 40 electrochemical techniques, this device is widely used in corrosion studies, energy research, materials science, and analytical electrochemistry. Additionally, with the use of a current booster, the device can extend its output current up to ±20A, ±40A, or ±100A, and supports a higher compliance voltage of up to ±30V.

Applications:

• Energy materials (Li-ion battery, solar cell, fuel cell, supercapacitors, etc);
  
• Reactive mechanisms of electrosynthesis, electrodeposition (electroplating), anodic oxidation, electrolysis;
  
• Metallic corrosion; corrosion inhibitor, coating and cathodic protection efficiency;
  
• Electrocatalysis (HER, OER, ORR, CO2RR, NRR, water splitting).
