Identical to the S2, except that the paddle is shorter for use with freely-moving recordings.

To make the freely moving MEAs assembly, you will need to solder wire leads (28 gauge copper varnished magnet wire) from the PCB paddle to 4 pins and insert them in the ABS connector socket (Ginder Scientific 9 pin ABS plug GS09PLG-220). Paddle and wires are epoxied (5 min epoxy) in place . End user must coat and prepare Ag/AgCl/ reference electrode before use and it must be soldered and epoxied into the connector to seal against moisture. The Ag/AgCl reference electrode wire must be kept dark and soaked in 3M NaCl a minimum of 12 hours prior to calibration to assure stable baseline.

For in stock items, orders usually ship 2-3 days after order is received.
