IonFlux Plates are microfluidic devices used exclusively in the IonFlux System for automated patch clamp assays. They are integrated into SBS-standard well plate formats for convenience and compatibility with automated liquid handling instrumentation. Multiple plate formats are available which correspond to the IonFlux system configuration. Each well on the plate has a dedicated function as either a compound well, cell trapping well, cell inlet or cell outlet well. This technical note provides an overview of the available plate formats.
