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.

The Cell Module provides investigators full apical and basolateral access to all wells. The handy docking station allows easy handling with no cables to unplug.

A magnetic mount makes handling of the upper electrodes comfortable and accurate positioning 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.
