Multichannel Systems EcoFlexMEA36 User Manual

EcoFlexMEA36

Flexible Microelectrode Array with 36 electrodes for use with
32-Channel Miniature Preamplifier MPA32I for in vivo or in vitro applications.

37 mm

Electrode field:
1800 x 1800 m, 32 recording electrodes,
2 reference electrodes, 2 ground electrodes

Connect the EcoFlexMEA36 directly to a 32-Channel Miniature
Preamplifier. Insert the EcoFlexMEA36 into the MPA32I with
the electrode field up. The additional connector can be used for
connecting a silver pellet or a silver wire for grounding the bath.

GND 1 is a large ground electrode connected to pin 1 of the MPA32I input connector. GND 2 is a second
ground electrode connected to pin 36. The REF electrodes are reference electrodes connected to pin 2
and 35, respectively. Both ground inputs and both reference electrode inputs are equal, that is, they are
connected to each other inside the standard MPA32I. Please see the MPA32I manual for details.

The numbers in the electrodes are the recording channel numbers that refer to the channel numbers
of the data acquisition program. Please make sure that you have selected “Configuration” in the “Channel
Layout” under “Data Source Setup” with a total number of 64 channels. In “Amplifier”, please choose
FA32I/S or FA64I/S and in “MEA” EcoFlexMEA36. In Layout tab of the display, please click ”Default Map”.

The letter digit code below is the electrode identifier and refers to the position of the electrode in the grid.

Important: The channel map is constructed by looking on the back side of the electrodes,
because the FlexMEA electrodes are placed on the preparation upside down!

If you use a MEA64-System with more than one MPA32I, the signal collector SC2x32 leads the output
channels of the second amplifier to channel numbers 33 to 64. Please read the SC2x32 data sheet.

Warning: The device may only be used together with the MPA32I from Multi Channel Systems

!

MCS GmbH, and only for the specified purpose. Damage of the device and even injuries can
result from improper use.
