SARASOTA – November 10, 2026 -- World Precision Instruments (WPI) has launched EVOM Auto ElectroZ, which extends its automated transepithelial/endothelial electrical resistance (TEER) platform with electrochemical impedance spectroscopy (EIS) across frequencies from 2 Hz to 100 kHz. The system is available now.
ElectroZ measures impedance from 2 Hz to 100 kHz in under 20 seconds
Conventional TEER measures resistance across a cell layer at a single frequency of 12.5 Hz. ElectroZ captures both resistive and capacitive properties of living cells in a measurement that often takes less than 20 seconds.
The software automatically calculates four parameters:
