Fast Piezo Solution Switcher
The piezo solution switcher
uses a high-speed piezo flexure guided nanopositioner to
move pipette tips in solution switching applications. It
can move an electrode tip across a 5 µm thick theta
glass septum. This system is ideal for measuring cellular
response to drugs or other elements in solution.
Piezo movement
can be triggered by either input from common recording amplifier
equipment or by Siskiyou software via a LabVIEW™ interface
that can control distance, frequency and dwell time. The
piezo also includes the piezo amplifier box and the Input-Shaping® board,
which significantly reduces pipette tip vibration and can
be programmed to virtually eliminate resonances from your
specific system.
The piezo flexure guided nanopositioner
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
angle. This adjustable fourth 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 also has a built-in coarse adjustment for rotation
of the entire manipulator, or can also be used with our MX-RS
rotation stage for more precise motion.
