nanoZ v1.4.0

The nanoZ includes several inbuilt electroplating modes for automated electrode impedance matching, activation, and cleaning. As the nanoZ utilizes a very low test current and only requires a computer with a USB port, it is easy to use and ideal for both in vivo and in vitro applications.

The nanoZ comes packaged with a 1.8m USB cable, an NZA-DIP16 adaptor for probes using a DIP16 connector, a 32 channel NZA CAL calibration adaptor, a 3-pin to alligator clip cable, and the software installation CD. Additionally, a Plexon/nanoZ adaptor specific to the headstage in use will be needed.

The nanoZ is fast, accurate and very easy to use, but only when using the appropriate adaptors bridging your electrodes to the nanoZ. Your Plexon Sales Engineer is ready to help evaluate the best set-up to meet your research needs.
