The ECIS® 24W Trans Filter Array electrically monitors the barrier function of cells grown in culture upon permeable membrane substrates. The new 24W transwell device accommodates standard 24 well membrane inserts from a broad range of manufactures. The adapter holds up to 24 inserts and is connected to the ECIS® data acquisition system, allowing up to 24 filters to be followed independently. Dedicated software presents real-time, continuous measurement of TEER in ohm-cm2.

ECIS® (Electric Cell-substrate Impedance Sensing) is a label free, non-invasive method to electronically monitor cells grown in tissue culture.
