Description
The EmStat4 MUX combines a high-performance potentiostat with an integrated multiplexer, enabling automated multi-sample electrochemical measurements. Its 8-channel architecture allows sequential testing of multiple electrodes or electrochemical cells using a single instrument.
Two operation modes are available :
Consecutive mode : completes one measurement before switching channel
Alternate mode : cycles between channels during measurement
This makes the system ideal for high-throughput experiments such as sensor arrays, screening studies, and parallel electrochemical testing.
