CWE Impedance Head Stage Super-Z

The Super-Z is an auxiliary ultra-high impedance amplifier head-stage for use with the BMA-931 bioamplifier module. FET electrometer input buffers are used to create the highest possible input impedance. That high impedance means the Super-Z can be used with any type of electrode, including tiny ion-specific microelectrodes, so it's well-suited for use in studying high-impedance cell-level signals. A stable input DC offset control allows you to null out electrode polarization potentials or other offset voltages, which can interfere with measurement accuracy. The Super-Z's switchable x1/x10 gain provides an overall range of 50 to 500,000x when used with the BMA-931. A five-step DC calibrator is standard. performance.
