EZ Assistant

EZ-Assistant is a motorized add-on that automates the up-and-down movement of your stereotaxic instrument, so you no longer turn the dial by hand. It connects to your existing mechanical rig and is operated from a compact controller. You set the speed and depth, and EZ-Assistant carries out the movement the same way every time.

• Programmable insertion speed: Set a constant insertion velocity to reduce variation from one operator to another and from one surgery to the next.
• Controlled withdrawal: Withdraw the needle slowly and consistently to help limit backflow of the injected solution (reflux) along the needle tract.
• Micrometer-scale positioning: Movements are repeatable to better than 1 µm*, which helps when targeting small brain structures.
• Simple interface:
  • Step controls: Fine-tune the reference point with the up and down arrows, from 1 to 9999 µm per click*.
  • Create sequence: Build a custom sequence, add delays and choose a speed (1–999 µm/s*) for each depth.
  • Save/Upload: Store and reuse up to 8 speed and position configurations.
• An affordable upgrade: EZ-Assistant is a cost-effective way to modernize a mechanical stereotaxic rig without replacing it.
