CUSTOMERS FEEDBACK

I've been a customer of Microprobes for Life Science for years and my lab has been using their products for even longer. Their microwire arrays and optogenetic-microwire arrays have always worked extremely well for us. We have used them to record in a variety of brain areas in rats and mice at both acute and chronic time points. The electrodes have always been in pristine condition, made to our exact specifications.
