Which EmStat instrument is suitable for me?

EmStat is available as single channel potentiostat. The more advanced EmStat Blue is wireless by means of its integrated Bluetooth radio and battery and has an auxiliary port for connecting extensions.

EmStat is also available combined with a multiplexer, as a polypotentiostat, or as multichannel potentiostat. The differences between these types of devices is explained here.

The EmStat and multiplexer boards are also available as OEM potentiostat for implementing EmStats in your device, e.g. in an e-QCM or e-SPR instrument.
