Transepithelial resistance meter(TEER)
Description
  • Low noise for better resolution and accuracy
  • Adjustable measuring currents (2, 4 or 10 µA)
  • Resistance from 1 Ohm to 100,000 Ohm or with three fixed current ranges
  • Reliable low-current, low-voltage design prevents transport of metal ions
  • Fast stabilisation of resistance on low levels below 200 Ohm with resolution down to 0.1 Ohm
  • Ergonomically designed tiltable stand for low glare
  • The display shows the most recent set of programmed parameters
  • Automatic plate indexing operation with or without control well subtraction for resistance and potential difference measurements
  • Continuous data recording via USB (PC, Mac, Linux)
  • Saves time-stamped data to a file that can be read in a spreadsheet on a USB stick
  • Scalable firmware

Benefits
  • Eliminates errors and reduces handling time
  • Automatic data recording
  • Small footprint
  • Electrode designed to be positioned above the well (12 or 24 well plate) without being held and always in the same position, for reproducible results
  • Easy calibration and verification
  • Triggering of the measurement with a foot switch for hands-free operation
  • Trans-epithelial resistance calculated by applying a formula using the unit area to the resistance

Applications
  • Measurement of confluence, transepithelial resistance or potential difference of epithelial or endothelial tissue
  • Permeability, conductance and drug effect studies
  • Continuous digital monitoring of a target membrane
  • Blood-brain barrier transport
  • Studies of lung epithelial tissue
  • Intestinal tissue studies
  • Skin tissue studies
