Metal Microelectrodes

We provide Metal Microelectrodes for a wide range of extra-cellular recording and stimulating applications. There are multiple configurations for maximum customization. 

Platinum-Iridium has a higher activation level, which causes it to deteriorate slower under current. It is less toxic in chronic applications.
