  1. Why Choose an EVOM3 Over an EVOM2 for TEER Measurement
    May 15, 2020
    After 12 years, the next generation of the EVOM is born. Used for measuring Transepithelial Electrical Resistance (TEER) and monitoring the confluence of cell monolayers in culture well plates the EVOM3 TEER Measurement System enables researchers to carry out experiments more efficiently by improving the workflow, and increasing the stability and accuracy of readings over that of the EVOM2.  Here are six of the EVOM3 improvements.    
  2. 7 Reasons to Love the New EVOM3 for TEER Measurement
    May 15, 2020
    The NEW EVOM3 Epithelial Volt/Ohm Meter delivers improved workflow efficiency, increased stability and more repeatable measurements than traditional Trans Epithelial Electrical Resistance (TEER) meters. Here are seven things you will love about the new EVOM3.     1. It has an intuitive Touchscreen Display Providing users with vital feedback during experimental measurements, the EVOM3’s large touch screen offers a range of informational views. The new graphical displays for trend analysis and measurement values helps you deliver a simple, stepwise methodology during experimental measurements. The touch screen interface has an intuitive, easy-to-use menu for configuration and calibration that is designed to eliminate human errors and reduce experimental processing time. 2. EVOM3 offers Auto Data Logging Eliminating the need to log data by hand, the EVOM3 writes the resistance or voltage information to a USB drive in CSV format for easy transfer to spreadsheets and data analysis programs. 3. With the EVOM3 you get Hands Free Recording When used with the footswitch, it enables hands-free recording of measurements. 4. You can make Quick, Easy, Reliable Readings At the heart of the EVOM3 is our latest processor and circuitry, providing users with quick, easy and reliable readings due to its fast stabilization, automatic twenty times sampling average and low noise d
  3. What's the Difference between Hanging and Standing Cell Culture Inserts used in EndOhm Chambers
    February 22, 2019
    WPI EndOhm chambers are used with WPI's EVOM2 meter for making TEER (transepithelial electrical resistance) measurements. Here Subhra shows the difference between hanging cell culture inserts and standing cell culture inserts.
  4. How to Set the Gap on your WPI EndOhm Chambers
    February 21, 2019
    WPI EndOhm chambers are used with WPI's EVOM2 meter for making TEER (transepithelial electrical resistance) measurements. Each EndOhm chamber comes with a "spacer" disk for calibrating the gap between the two chamber electrodes. A consistent gap ensures reliable measurements. Here Subhra shows how to calibrate your chambers.
  5. Resurfacing Electrodes in a WPI EndOhm Chamber
    February 21, 2019
    WPI EndOhm chambers are used with WPI's EVOM2 meter for making TEER (transepithelial electrical resistance) measurements. After heavy use your background resistance measurement may start to rise. Your electrodes may need to be resurfaced to remove buildup of proteins, sugars and biological materials. Here Subhra demonstrates how to clean and resurface your EndOhm chambers.
  6. Choosing an EndOhm Chamber Compatible with your Cell Culture Inserts
    February 21, 2019
    WPI's EndOhm chambers are used with WPI's EVOM2 meter to measure TEER (transepithelial electrical resistance) in cell culture inserts. Three chamber sizes are available for 6-well plates, 12-well plates and 24-well plates. Here Subhra demonstrates how to choose an EndOhm chamber to match the cell culture inserts you are using.
  7. Prevent Damage to Snapwell Inserts by Using STX3 Electrode
    February 21, 2019
    The WPI EVOM2 meter is used to measure TEER (transepithelial electrical resistance) in cell culture inserts. The STX2 electrodes with a static length may cause damage to Snapwell inserts. Here Subhra demonstrates how to use the adjustable STX3 electrode to prevent damage to your cell culture inserts.
  8. EVOM2-How to Equilibrate Your STX2
    April 24, 2013
    The World Precision Instruments (WPI) EVOM2 is used for making trans epithelial electrical resistance (or TEER) measurements. Two silver/silver chloride pellets are used for the electrodes. The chloride ion tends to migrate, which is a reversible reaction. But, because of this chloride ion swapping, the electrodes need to be polarized before each use. Before using the meter for making voltage measurements, equilibrate the electrodes. This video shows you how.   More Info
