ISO 9001:2015 Certified MEA Production

Microelectrode Arrays (MEAs) from Multi Channel Systems are produced by NMI Technologie Transfer GmbH (NMI-TT), a company dedicated to applied research using utmost biocompatible materials. Founded in 2002 as a subsidiary of the NMI Natural and Medical Sciences Institute at the University of Tübingen, NMI-TT and Multi Channel Systems have collaborated on many projects over many years. ISO 9001:2015 certified production ensures that every MEA meets excellent and consistent quality standards.

MEAs with 32, 60, 120 or 252 Electrodes

Standard MEAs fit in MEA2100-Systems, MEA1060 amplifiers, and the USB-MEA256-System. Electrodes are coated with titanium nitride (TiN), a very stable material that guarantees MEAs can be reused several times. The majority have glass carriers, facilitating examination under any upright or inverted microscope.

Key Features

• Available with opaque (titanium) and transparent (ITO) tracks and contact pads
• Most types available with internal reference electrode replacing the Ag/AgCl pellet in the bath
• Long life — can be reused several times
• Electrode layouts for all applications
• Electrodes with very low impedance
• Electrodes as small as 8 μm in diameter
• Perforated MEAs available for excellent electrode-contact
• All ring options (glass or plastic): height 6 mm
• Custom layouts available on request

Multiwell Plates for High Throughput

For medium and high throughput applications, Multiwell plates with 24 or 96 wells are available for drug screening or toxicity testing.

• TiN electrodes on glass: 24 wells, 12 electrodes/well, 30 μm electrode diameter, 300 μm spacing — ideal for neuronal cultures
• Gold electrodes on epoxy: 24 wells (12 electrodes/well) or 96 wells (3 electrodes/well), 100 μm electrode diameter, 700 μm spacing — ideal for iPSC-derived cardiomyocytes

Flexible MEAs for In Vivo and Ex Vivo Recordings

FlexMEAs feature electrodes embedded in a thin, highly flexible polyimide foil. This flexibility allows tight attachment to the surface of brain or heart preparations. Available with 24, 36 or 72 electrodes of gold or TiN on polyimide foil, FlexMEAs are the ideal solution for recordings from multiple species in both acute and long-term chronic experiments.
