Potentiostats

The instruments at the center of electrochemical research — built for accuracy you can publish, with the specifications documented, not estimated.

17 instruments
// Reference line · high performance

The instruments you reach for when the measurement is hard

Highest resolution, widest EIS bandwidth, and published accuracy contour plots. The Reference line is what goes on the bench when the current is femtoamps, the impedance is milliohms, or the reviewer will ask.
