This direct drive, single-axis micropositioner is designed specifically for positioning microelectrodes or probes in a stereotaxic apparatus with speed and precision adequate in extracellular experiments. The system consists of a small footprint controller box, an easy to use handset and a slim drive unit mountable in most stereotaxic arm manipulators. An international power supply is included. An economic yet professional solution for stereotactic positioning. Not for use in human applications.
