EPS™ - Electrode Positioning System
Key Features


Specially designed micropositioner with flexible shafts for multi-electrode placement in restrained subjects

Compatible with the Flex MT and MultiDrive

  • Optimize data collection with accurate and independent multi-electrode placement.

  • Improve the quality of neural recordings by recording lean and stable neural signals. 

  • Maximize your research by recording crucial data from all electrodes.




The Alpha Omega EPS is a state-of-the-art micropositioner designed for the accurate placement of microelectrodes in acute in vivo experiments. 

The system gives the user maximum flexibility, allowing control of each individual electrode during an experiment, with no noise interference. Moving the electrodes smoothly and independently enables the user to execute research with greater control and precision than ever before.

Key Features and Benefits
  • Micron precision. The EPS is exceptionally precise. Software controls the electrode movement with micron precision.
  • Electronic control. An easy-to-use software interface ensures accurate, computer controlled electrode
  • Flex MT and MultiDrive compatible. The EPS easily connects to any AlphaOmega microdrive to provide precise control of every electrode.
  • Complete control. Drive all electrodes simultaneously or position a single electrode at a time.
  • Quick and easy setup. The EPS system is easy to setup and operate, reducing the time it takes to perform each experiment.
  • Speed control. Select an entry speed between 5-400 microns/second for each electrode.
  • Expandability. Choose between 1 to 4 motors per EPS box, and add up to 8 boxes to independently control 1 to 32 electrodes.
  • Remote control. Control the electrode movement from inside the recording room through an easy-to-use joystick interface that allows complete control over each electrode.
  • Reliability. Alpha Omega’s EPS system is durable and reliable, with some customers using the system for over 10 years without the need for service and without the loss of precision.
  • Motor separation. The EPS was specially designed with flexible shafts to separate the motors from the microdrive, significantly reducing the chance of interference that occurs in comparable systems.
  • Independent or group control. All electrodes can be positioned independently as needed, or controlled in user-defined groups for simultaneous control.
  • Less weight. The motor box has been specifically designed to be mounted; electrodes are controlled through flexible shafts to minimize the weight on the chamber 
  • Limitless layout options. Flexible shafts allow a single motor box to connect to a variety of micropositioner layouts, making the connection to any Flex MT or MultiDrive easy. Additionally, it’s simple to connect to more than 1 chamber at a time, or to use multiple terminals in one chamber
