How You Improve Your Research Results When You Upgrade

For over 30 years, WPI has been perfecting the equipment for measuring Transepithelial Electrical Resistance (TEER). Researchers have relied on WPI's EVOM™ technology for the development of well over 16,000 peer-reviewed published research papers that use WPI TEER measurement meters! Here we compare the commonly used TEER meters in laboratories today. At a glance you can see the evolution of WPI's TEER technology and learn why it is the industry's standard TEER measurement methodology. Here's some of the benefits of upgrading to the EVOM™ Manual.

  • More stability means more accurate readings
  • No need to track data by hand
  • Variety of measurement ranges for your use with many cell types
  • Hands-free recording for faster sample analysis
  • Touchscreen display for easy of use and data display
  • Upgraded electrode options for many applications
