cellZscope 2
... automated and easy-to-use TEER and Ccl measurement in 24 individual wells.

Like all cellZscope systems, the cellZscope2 is computer-controlled and allows automated and reliable measurements of the ohmic resistance (TEER, transepithelial / -endothelial resistance) and capacitance (Ccl) of the cell layers in real-time.

Main features are:

  • Easy readout parameters: TEER and Ccl of the cell layer.
  • Full compatibilty with a broad range of standard cell culture inserts.
  • Standard time resolution: 1 measurement per well every 4.5 min.
  • Handy docking station facilitates hassle-free handling before, during and after the experiment.
  • Automated fast process monitoring as well as reliable long term measurements over days and weeks.

cellZscope2 - Lid with upper electrodes

The upper electrodes are magnetically attached to the lid. Easy exchange is guaranteed.

Three well sizes are available for use with small (“24-well” type), mid-sized (“12-well” type), or large (“6-well” type) standard cell culture inserts, respectively.
