Microelectrode array (MEA) with the industry's lowest-impedance electrodes

The MED Probe has multiple microelectrodes embedded in the center of a transparent glass plate. The surrounding glass (or plastic) cylinder makes the MED Probe a self-contained recording chamber.

The MED Probe features the industry’s lowest-impedance electrodes (10 kΩ at 1 kHz for 50 μm electrodes). It provides excellent signal-to-noise ratio and capabilities of stimulation.

• The MED probe allows users to stimulate and record fromsamples using planar Microelectrodes

Several types of arrays are available:

• 8 x 8 (64) electrode arrays are available with four different inter-electrode spacing’s; 100, 150, 300 and 450μm. Each patented micro-electrode measures 50μm x 50μm – except for the 100μm spacing configuration, with micro-electrodes measuring 20μm x 20μm

• A 61 electrode hexagonal array is available with a 70μm interelectrode spacing. The electrodes are circular (20μm diameter)

• Two special arrays, designed specially for simultaneously stimulating / recording from the dentate gyrus (DG), CA3 and CA1 are also available for mouse and rat hippocampal slices
