Thomas Motorized Electrode Manipulator (MEM)™
40mm electrode travelThomas Dual Probe MEM
Up to 40mm electrode travel
The Thomas Motorized Electrode Manipulator (MEM)™ is a small and lightweight low-cost microdrive system for extracellular recordings. This microdrive can be used with different conventional extracellular recording electrodes and preamplifier systems presently available on the market. The microdrive consists of a precision drive motor, a guide tube unit and a holder for mounting the microdrive to different stereotaxic setups like shown in the gallery. The Dual Probe MEM is able to move two different probes simultaneously with high positioning accuracy.
Key features:
- Low-cost precision microdrive system
- Electrode travel distance: up to 40 mm
- Number of simultaneously moveable probes: 2
- Axial resolution better than 1µm, x-y-Positioning with a grid
- High precision & quality “Made in GERMANY” by Thomas RECORDING
- Variable speed range from 0…250 µm/s, higher velocity on request
- Custom-made solutions for each recording application
- Modular number of drives mountable to the chamber holder
- Networkable motor control unit (LAN communication via TCP/IP)
- Special designed electrode holder prevents bending of electrodes at the top

The MEM System is adapted to your special requirements (e.g. MEM holder is customized so that it fits to your stereotaxic instrument).
The dual probe Motorized Electrode Manipulator (MEM) is available with 40 mm electrode travel distance. This Microdrive was designed to move up to two multicontact probes like the Thomas Multitrodes (8-, 16-channel) and the Plexon U-, V- and S-probes simultaneously.

Figure 3 shows a dual probe MEM with 40 mm electrode travel distance mounted to a squared recording chamber. The MEM is equipped with a joint holder that allows to cover the complete chamber grid xy-area to place the guide tubes. This is an example for the customization of the MEM system. We can adapt our system to each research application. Please do not hesitate to contact us!
