High speed penetration and precise control The piezo-ceramic element in WPI’s MPM10 provides high penetration speed over an extremely short distance (0.5 to 10.0 µm). Because the range of travel of a dedicated piezomanipulator is much too limited for it to be useful independently, it must be mounted on a manipulator. The MPM-10 piezo translator combined with a DC3001 motorized micromanipulator (available separately) provides a single electronically controlled system. When the piezo element is activated, the MPM-10 axis carrying the micropipette shoots forward at a rate which is set on the control panel, then immediately returns (at a slower speed) to its starting position. As soon as the piezo element begins its reverse travel, the motorized manipulator starts to travel forward. The complimentary opposition of these two travel sequences results in the micropipette tip remaining in its advanced absolute position. The three axes of the DC3001 are controlled by six buttons. Pressing a button for less than 0.3 seconds activates one step, the size of which (0.5 to 10.0 micron) is set on the Step Size control. Pressing longer activates the continuous mode, at the rate set on the Motor Speed control. Pressing the button for the X axis forward direction activates the piezo mode. Advancement speed of the piezo element can be separately adjusted from 1 to 100 mm/sec. Precise construction and special vibration stabilizers ensure the MPM-10’s excellent MPM10 Piezo-Translator Adapter MPH8 allows use of WPI electrode holders! MICROMANIPULATORS DC3001 micromanipulator and M-3 tilting base not included. puncture characteristics. Lateral deviation from the ideal axis of puncture (measured at the tip of the electrode holder) is ± 5% of the step size.

Piezo Translator For use with M3301 and DC3001 micromanipulators Especially recommended for use with the M3301 micromanipulator, the MPM20 is a very efficient tool for intracellular injection. High penetration speed and precise axial advance allows injection pipette to be brought to its target position with tremendous accuracy. Lateral escape of the cell is almost eliminated, and even tough membranes can be penetrated. Independently selectable reverse speed setting can be used for fast withdrawal, preventing adhesion of the injected cell to pipette tip. Mounts directly onto DC3001 and M3301 micromanipulators. Use with DC3001 requires MS314 controller (for the micromanipulator). The combination of the MPM20, a micromanipulator, and the PV820 PicoPump (see page 180) constitutes an extremely efficient system for intracellular injection; cell penetration, injection and withdrawal are executed automatically with the press of a button.
