- The piezo-translator PM 10 is specifically designed
for the penetration of cell membranes in the context of electrophysiological
investigations. The Piezo element is mounted on the motorized X-axis
of the micromanipulator DC 3K (has to be ordered separately)
- By way of this combination, piezo-stepper with a motoried
micromanipulator, the advantages of both systems can be combined in
an ideal fashion. Through the use of a piezo-stepper head high penetration
velocities after a very short travel distance and vibration free movement
over long paths can be achieved with the motorized micromanipulator.
- The piezo-element and all three axes of the micromanipulator
are activated by one control unit. Single steps of 0.5 to 10 µm
are initiated by pressing a button briefly (0.5 sec.). The advance velocity
of the piezo stepper can be set separately to 1-100 mm/sec.
- Pushing the X-button for a longer period triggers the
smooth continuous motorized advance, the speed of which is also selectable.
- For a successful penetration of a membrane a vibration-free
axial movement is required.
- Through narrow manufacturing tolerances and special
oscillation damping stabilizers excellent penetration capabilities have
been achieved.
- The deviation from the ideal axis measured at the tip
of the pipette holder (the site of the microelectrode) is less than
±5% of the step size, typically only ±2.5% which means
for a µm step only about ±0.25µm.
