IMX8 Electrochemical Multiplexer

The IMX8™ Electrochemical Multiplexer is an affordable way to expand the throughput of your lab. Experiments can be sequentially multiplexed on up to 8 channels. The IMX8™ is ideal for corrosion inhibitor testing, EIS evaluation of paints/coatings, monitoring of field probes for corrosion tests, and chemical sensor development.

Key features include:

  • 8-channel for sequential measurements
  • DC and AC experiments
  • Industry standard multiplexed experiments

Product Details


The IMX8™ Electrochemical Multiplexer partners with a Gamry Potentiostat to convert a single potentiostat into a powerful instrument suitable for sequential multichannel operations. It allows you to sequentially take measurements on up to eight electrochemical cells. The IMX8™ Multiplexer is great for automating repetitive experiments, and for increasing throughput on long-term experiments where data can be taken periodically. Each of the eight Multiplexer channels also incorporates a "local" potentiostat to polarize the sample when not participating in the electrochemical experiment. The IMX8™ is not usable for simultaneous multichannel experiments across multiple cells. For simultaneous multichannel experiments see the multichannel potentiostat.

*Note that EIS through the multiplexer is limited to 100 kHz
