DESCRIPTION 

1. Dual Functionality: The amplifier supports both voltammetry (measuring potential vs. current relationships) and amperometry (measuring current at a constant potential), allowing it to be used for a broad spectrum of electrochemical applications.
2. Wide Voltage Range: It offers a wide output voltage range of up to ±10V and allows for adjustable sweep rates (from 1 mV/s to several V/s), enabling precise control for a variety of experimental needs.
3. High Precision: The VA-10 provides high input impedance (>10 MΩ) and low output impedance, ensuring minimal interference with the electrochemical cell and maintaining signal accuracy in both three-electrode setups (working, reference, and counter electrodes).
4. Current Range & Sensitivity: The amplifier supports current ranges from 0-100 µA and is highly sensitive, capable of detecting nanoampere (nA) to picoampere (pA) currents, making it suitable for low-level electrochemical measurements.
5. Low Noise and High Stability: Designed with low noise characteristics, the VA-10 ensures highly stable and precise readings, even in challenging environments where small signals need to be measured accurately.
6. High-Frequency Response: The amplifier’s high-frequency response makes it capable of accurately measuring both low and high-speed electrochemical processes, which is critical in time-sensitive experiments.
7. Power Supply and Outputs: The amplifier operates on a ±15V or ±12V power supply, and it supports both analog and digital outputs, allowing integration with external data acquisition systems for real-time monitoring and analysis.
8. Software Control: The VA-10 is compatible with software control, providing easy setup, monitoring, and data logging for experiments, ensuring seamless integration with laboratory setups.
