What Are B-Stock Probes?
All NeuroNexus probes undergo extensive electrical and mechanical testing and inspection for all electrode channels before leaving our lab. At times, select probes exhibit a few channels with electrical shorts or open sites (out of 16/32/64 available), but are otherwise perfectly functional. These probes therefore do not pass our normal quality checks, and become B-Stock probes.
We typically have B-Stock probes in a variety of electrode and package combinations. All B-Stock probes are fully assembled, can be shipped immediately, and are discounted based on the number of irregular channels. Irregular channels are identified in the delivery documentation shipped with every order.
