🔹 VersaSTAT3A – Potentiostat Galvanostat

VersaSTAT3A sets the standard for value, flexibility, and floating operation. Its floating measurement capability enables experiments on ground-connected cells and structures, making it ideal for fuel cells, corrosion studies, and autoclave-based testing. When paired with another floating unit, it also supports bi-potentiostat RRDE experiments.

Key Points:

• Floating operation

• Optional 20 A booster

• Ideal when high current is not always required

🔹 VersaSTAT4A – Potentiostat Galvanostat

The VersaSTAT4A is the high-speed flagship of the VersaSTAT family, featuring 500 kS/s data acquisition. Like the 3A, it offers floating capability for grounded systems and is well suited for advanced electrochemical dynamics and RRDE experiments.

Key Points:

• Floating operation

• High-speed measurements (500 kS/s)

• Optional 20 A booster

🔹 VersaSTAT3 – Potentiostat Galvanostat

VersaSTAT3 delivers similar electrical performance to the VersaSTAT3A but without floating capability. It is only available with a 20 A power booster and is recommended when high current is always required and floating operation is not needed.

Key Points:

• Non-floating operation

• 20 A booster included as standard

🔹 VersaSTAT4 – Potentiostat Galvanostat

The VersaSTAT4 mirrors the VersaSTAT4A’s specifications but does not support floating operation and is only supplied with a 20 A booster. It is suited for high-current applications where floating measurements are not required.

Key Points:

• Non-floating operation

• 20 A booster included as standard

🔹 VersaSTAT3F – Potentiostat Galvanostat

The VersaSTAT3F offers specifications similar to the VersaSTAT4A and is always supplied with a 20 A booster or integrated as part of VersaSCAN scanning electrochemical systems. When a booster is not required, the VersaSTAT4A is the preferred alternative.

Key Points:

• 20 A booster required

• Optimized for VersaSCAN integration
