4.15 Quadrant MEA: 60-4QMEA1000
60-4QMEA1000iR-Ti
The 60-4QMEA1000 has 60 electrodes organized in four quadrants (13 electrodes each) with a center line
(7 electrodes). The electrode diameter is 30 μm, and the interelectrode distance varies: Inside the quadrants
the distance is 200 μm, from quadrant to quadrant the distance is 1000 μm, and to the center line it is
500 μm.
The 60-4QMEA1000 is available with an internal reference electrode.
The flat, round electrodes are made of titanium nitride (TiN). MEAs with TiN electrodes are very stable.
Therefore, the MEAs can be reused several times and are perfect for long-time experiments (up to several
weeks and even months). The electrode impedance ranges between 30 k and 50 k
Tracks are made of titanium (Ti) and contact pads are made of titanium nitride (TiN); insulation material
is silicon nitride (SiN).
Using 60-4QMEA1000
The 60-4QMEA1000 can be used for a wide variety of applications. They are robust and heat-stabilized.
They can be autoclaved and coated with different procedures for cell and tissue cultures. Generally,
they can be used for acute experiments as well as long-term cultures.
