A system for high-throughput analysis of membranous samples having ion channels including at least one membranous sample, a multi-compartment structure including an extracellular chamber, an opposing intracellular chamber and a partition separating the extracellular and intracellular chambers, the partition having a plurality of apertures fluidly and electrically coupling the extracellular and intracellular chambers, wherein at least one of the apertures is sealed by the at least one membranous sample, and another of the apertures is unsealed, a electric source configured to apply a current between the extracellular and intracellular chambers, wherein a portion of the current travels through the unsealed aperture, and a current sensor configured to measure the current between the extracellular and intracellular chambers. A method of using the system is also disclosed.
