Thomas Electrode Micro Matrix System
Thomas Electrode Micro Matrix System
The Thomas Electrode Micro Matrix is a small and lightweight microdrive system for electrode recordings. The system consists of a single miniaturized microdrive system, which is equipped with a single core microelectrode. A single channel preamplifier and a precision motor is integrated in the single drive system shown in figure 1.
The Thomas Micro Matrix is also available for the use with Tetrodes.
Key features:
- High precision & quality “Made in GERMANY” by Thomas RECORDING
- Axial resolution better than 1μm, x-y-Positioning with a grid or xyz manipulator
- Patented rubber-tube drive, no hysteresis, slick or free motion due to patented rubber tube drive (avoids drawbacks of cable, direct or hydraulic driven systems)
- Flexible electrode travel range by chassis extension
- Variable speed range from 0…250μm/s, higher velocity on request
- No 50/60Hz noise pickup from the environment
- No electrode connection cables free in air!
- Integrated 1 channel electrode preamplifiers
- Custom made solutions for each recording application
- Stable long-term recordings with thin microelectrodes for hours

The Thomas Tetrode Micro Matrix is a very lightweight and flexible drive solution for Thomas microelectrodes. It is a modular microdrive concept. One can mount multiple of these drives simultaneously on a recording chamber like shown in figure 2 or just one drive like shown in figure 3.
It is possible to adapt the Thomas Electrode Micro Matrix to other stereotaxic instruments. Please do not hesitate to contact us for a custom-made adaptation of the Thomas Electrode Micro Matrix System to your special recording setup!
Advantages
- Each electrode is completely shielded against noise pickup from the environment
- The patented rubber tube drive does not cause any slick or free motion like cable or hydraulic or thread rod driven microdrive systems
- Adaptation to different electrode travel distances for cortical or deep brain recordings
- Modular system
- Networkable software to control one recording setup with up to 16 electrodes from different workstations by more than one neuroscientist
- System uses thin microelectrodes with high recording quality (e.g. Thomas electrodes)
- Low price
- Relatively small size and weight
- Easy setup and many features more
