• Rapid, precise impedance testing • Automated electroplating modes • 64 Channels for microelectrode arrays

Introducing the nanoZ Multichannel microelectrode arrays for neuronal recording require testing of electrode site impedances to identify faulty sites, and conditioning of sites for effective microstimulation. Manual methods are labor intensive. The nanoZ was specifically designed for testing multichannel electrodes, and has several electroplating modes for automated impedance matching, site activation, and site re-juvenation. It uses very low test currents for in vitro or in vivo testing, and can accurately measure the impedances of a 64-channel electrode in just 15 seconds. PC-based design We...

Intuitive software suite An intuitive user interface makes the nanoZ easy to use. In addition to manual operation, several fully automated modes are pre-programmed, including: whole-electrode impedance diagnostics, electrode impedance spectroscopy, electrode site cleaning/rejuvenation, and electroplating with precise control over current magnitude and time (e.g. for multichannel impedance matching, or delivering electrical current for lesioning or tissue marking). The test signals and electroplating waveforms are fully configurable. Virtual DMM and oscilloscope displays provide user feedback....
