Overview

Founded in 2002 as a subsidiary of the NMI Natural and Medical Sciences Institute at the University of Tübingen (www.nmi.de), the NMI Technologie Transfer GmbH (www.nmi-tt.de) is a company dedicated to applied research which produces high-quality MEAs using utmost biocompatible materials. NMI, NMI-TT and Multi Channel Systems have collaborated on many projects over many years. The MEA production is ISO 9001:2015 certified, so quality controls and standardized production processes ensure that the MEAs are always of excellent and consistent quality.

In order to supply MEAs for all different types of recording systems and to cover as many applications as possible, Multi Channel Systems has plenty of MEAs in its portfolio. Please click on the description tab above and learn more about our different MEAs.

Description

MEAs with 32, 60, 120 or 252 electrodes

These MEAs fit in MEA2100-Systems, the MEA1060 amplifiers, and the USB-MEA256-System. The electrodes are coated with titanium nitride (TiN), a very stable material, which guarantees that the MEAs can be reused several times. The majority of the MEAs have glass carriers, which facilitate the examination of the sample under any upright or inverted microscope. Tracks and contact pads are available in opaque and transparent versions and most MEAs have internal reference electrodes.

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 layout 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 (other heights on request)
Custom layouts are possible. Please contact us with your request.

Multiwell Plates

For medium and high throughput, the Multiwell-MEA-System is the ideal solution. Multiwell plates with 24 or 96 wells are available for drug screening or toxicity testing. Currently, we offer two types of multiwell plates:

Titanium nitride (TiN) electrodes on glass substrate

Available with 24 wells with 12 electrodes per well
Electrode diameter: 30 µm
Electrode spacing: 300 µm
Ideal for neuronal cultures

Gold electrodes on epoxy

Available with 24 wells (12 electrodes/well) or 96 wells (3 electrodes/well)
Electrode diameter: 100 µm
Electrode spacing: 700 µm
Ideal for (iPS cell derived) cardiomyocytes

Flexible MEAs

When doing in vivo/ex vivo recordings, flexible MEAs are the ideal solution. The elctrodes of FlexMEAs are imbedded in a thin and very flexible polyimide foil. This flexibility allows the attachment of the MEAs tightly to the surface of brain or heart preparations.

FlexMEAs are available with 24, 36 or 72 electrodes of gold or titanium nitride (TiN) on polyimide foil and are the perfect solution for recordings from several species, in both acute and long-term chronic experiments.
