EVOM Auto for TEER measurement in 96 HTS plates

Code EVA-MT-02-01

World Precision Instruments (WPI), the global leader in TEER technology introduced the EVOM™ Auto, the newest entry into WPI pioneering EVOM family of products. The EVOM™ Auto automates measurements of TEER in epithelial or endothelial monolayers cultured on high throughput screening 96-well plates utilizing our innovative EVOM technology, qualitatively measuring cell monolayer health and quantitatively measuring cell confluence by determining an increase or a plateau in tissue resistance.

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 produces a low AC current that avoids electrode metal deposits and is specially designed for the non-destructive, high throughput screening of epithelial monolayer confluence in cell cultures.
