    Amplifier VA-10 Voltammetry / Amperometry

    The VA-10 from npi electronic GmbH is an amplifier designed for voltammetry and amperometry, combining ease of use with picoamp sensitivity. It enables precise voltammetric recordings to be made over a wide voltage range (±1000 to ±2000 mV) and DC amperometry to be used easily thanks to its built-in voltage source. Compatible with carbon fibre electrodes and in vivo recording, it offers multiple Bessel filters, adjustable gain and a very high input impedance to detect the weakest signals. Also available as a module for the EPMS-07 system, it is a high-performance solution for sensitive electrochemical measurements.
