Portable EVOM™ Manual Simplifies TEER Measurement
Save Time with Advanced Features

WPI's EVOM Technology has been cited in thousands of peer-reviewed research articles. You've placed your trust in our TEER measurement line for nearly 40 years as the premiere innovator and manufacturer of EVOM meters, REMS, and Millicell ERS2. EVOM Manual is the original and still the gold standard in TEER measurement.

TEER is used for evaluating physiological properties like cellular confluence or monolayer integrity, barrier function, and 3-D tissue function. 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 EVOM™ Manual produces a low AC current that avoids electrode metal deposits and is specially designed for the non-destructive testing of epithelial monolayer confluence in cell cultures. Additionally, resistance readings are unaffected by membrane capacitance or membrane voltage. WPI’s state of the art EVOM™ technology provides you with real time valuable feedback during experiment measurements.

Automated measurement of tissue resistance in cell culture microplates provides the advantages of speed and precision, minimizes the chances of contamination, and ensures the rapid availability of measured resistance data. EVOM™ Auto applies a 12.5 Hz square wave current with switching polarity, which mitigates the chances of charging the sample and nullifies the chances of measurement technique having any adverse effects on the sample. Therefore, it is considered non-invasive measurement. EVOM™ Auto is designed for the non-destructive, high throughput screening of epithelial monolayer confluence and barrier function studies in cell cultures.

EVOM™ Manual with the help of different electrode options can measure cell layer resistances in different transwell formats (6, 12, and 24-well) removable inserts or in 24 and 96-well high throughput screening (HTS) plates. EVOM™ Manual can store data in an USB flash drive, which can be easily accessed by a computer.
