Details
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.
Complimentary opposition
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.
Multiple controls
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
Precise construction and special vibration stabilizers ensure the MPM-10’s excellent puncture characteristics. Lateral deviation from the ideal axis of puncture (measured at the tip of the electrode holder) is ± 5% of the step size.
