WPI's EVOM system is popular in the research community, both in academia and in industry, and it is commonly used for the evaluation of mammalian cellular health by measuring transepithelial/transendothelial electrical resistance (TEER or TER) of cellular layers.
EVOM™ Manual is powered by the same EVOM™ technology as older EVOM models (EVOMX, EVOM, EVOM2 and EVOM3). It has advanced features for performing experiments more easily. With the new touchscreen display you can now store data as Microsoft® Excel files on a USB flash drive. Just remove the flash drive with all your recorded data from the EVOM™ Manual and plug it into a computer to access and plot your data. It is as simple as it sounds.

EVOM™ Manual is WPI’s newest instrument to measure Trans Epithelial Electrical Resistance (TEER). Let’s look at how to set it up and take voltage measurements.
- Power on the EVOM™ Manual using the power switch on the rear panel.
- Insert the USB flash drive provided with the system into the USB port on the side of the meter.
- By default, the filename is plate1. You may choose a prefix that auto-indexes or a unique file name:
- Press and hold the Store button on the main screen for 2 seconds or press Store Screen on the Setup menu to configure your stored data files.
- To use a prefix and auto-indexing, activate the Auto Index radio button. Auto indexing sets the name to a numeric sequence with the name, a prefix and a sequential number (name_prefixN). Then, press Store Prefix to enter a file name. Or, to use a unique file name, deactivate the Auto Index radio button. Then, select File Name to enter a new name.
- Press Clear.
- Use the keypad to enter a new name.
- Press Enter.
- Press Setup to access...more

WPI’s EVOM™ Manual is the gold standard for delivering stable and repeatable Trans Epithelial Electrical Resistance (TEER) measurements. The EVOM™ Manual qualitatively measures cell monolayer health and quantitatively measures cell confluence by determining an increase or a plateau in tissue resistance detected using our innovative EVOM™ technology. The main display window has lots of information. Here’s a quick overview. You can download the infographic for a handy reference.

An Ussing Chamber is used when performing barrier studies across an excised epithelial tissue. Similar measurements can be made in well plates using an EVOM series TEER Measurement Meter, which is used for epithelial tissue that is grown to confluence in a cell culture well. While EVOM measurements are only qualitative, your throughput is much greater with an EVOM3. The EVOMs are portable and much more economical than an Ussing Chamber. Here Ben Dubansky, PhD explains the differences between EVOMs and Ussing chambers.

The EVOM is a special kind of voltmeter for measuring electrical properties across a layer of cells in culture or a biological membrane. It is the most commonly used commercial system for measuring across a layer of cultured cells. We are measuring TEER (TER) - Transepithelial Electrical Resistance. The EVOM3 allows us to zoom in and measure either resistance or voltage across these membranes or cells in culture.
