MXPZT-300 Series Solution Switcher

The MXPZT-300 series solution switcher uses a high-speed piezo flexure guided nanopositioner to move pipette tips in solution switching applications. It switches theta glass solution streams with respect to the recording electrode very close to the theoretical maximum velocity; typical cellular response curves are under 200 microseconds. This sys­tem is ideal for measuring cellular response to drugs or other elements in solution.

Piezo movement is triggered by input from common recording amplifier equipment that can control distance, frequency and dwell time. The MXPZT-300 includes the piezo amplifier box and the Input-Shaping® board, which significantly reduces pipette tip vibration. It can be re-programmed to virtually eliminate resonances unique to your specific configuration.

The piezo flexure guided nanopositioner with 250 microns of lateral travel is mounted to our ultra-stable MX1640 crossed roller microma­nipulator. The MX1640 has 20mm of travel in all four axes. The fourth axis can be set at any angle to select the desired approach. This axis incorporates our MXC-45 to allow rotation of the piezo/pipette assembly up and out of the experiment for easy glass replacement. The base of the MX1640 has a built-in coarse adjustment for rotation of the entire manipulator or can be used with our MX-RS rotation stage for more precise motion.
