INTRODUCTION
EVOM3 is the WPI’s newest instrument to measure Trans Epithelial Electrical
Resistance (TEER) measurement. The EVOM3 has been re-engineered to facilitate
ease of accurate, repeatable measurements and transfer of data. You no longer need
to log data by hand. The resistance or voltage information is written to a USB drive
in a format (CSV) that can be opened by most spreadsheet programs on either PC or
Mac. The processor controlled instrument is more stable and accurate. Included is a

measurements, and an overrange display feature eliminates false readings. The

The STX2-PLUS electrode was redesigned for easier insertion into and 24-well
plates and to be location re-placeable in the insert for repeatable and consistent
measurements. The new shielded electrodes are now designed to minimize electrical
interference and to be more easily maintained.
