EVOM3, Epithelial Volt/Ohm (TEER) Meter 3

TEER measurement with automatic data logging

  • Low noise design offers greater resolution and accuracy
  • Automatic 20X sample averaging improves accuracy and stability
  • Adjustable fixed measurement currents (2, 4 or 10 μA)
  • Resistance auto ranging from 1 Ω to 100,000 Ω or with three fixed current ranges
  • Reliable low current, low voltage design prevents metal ion transport
  • Fast resistance stabilization on low levels under 200 Ω with resolution to 0.1 Ω
  • Ergonomic tilt stand for low glare operation
  • Graphical display of popular plates (6, 12, 24, 96) for trend analysis
  • The display shows the most recent set of parameters
  • Automatic plate indexing operation with or without control well subtraction for resistance and potential difference (PD) measurements
  • Continuous data logging via USB (PC, Mac, Linux)
  • Saves date stamped data to a spreadsheet readable file on a USB drive
  • Upgradable firmware

EVOM3 benefits

  • Eliminates errors and reduces experimental processing time
  • Auto data logging eliminates the need to track data by hand
  • The small footprint allows more bench space
  • Easy calibration and verification
  • Footswitch for hands-free recording
  • Prevent data loss with auto save and data recovery when battery is low
  • TEER is easily computed by applying a unit area formula to the resistance

Applications of EVOM3

  • Measure epithelial or endothelial tissues for confluence, TEER and potential difference
  • Permeability, conductance and drug studies
  • Continuous digital monitoring of a target membrane
  • Common studies
  • Blood-brain barrier transport
  • Lung epithelial tissue studies
  • Intestinal tissue studies
  • Skin studies
