The flagship in our line of precision micromanipulators,
the motorized MP-285 is affordable yet offers advanced features
found in manipulators costing thousands more. Custom engineered stepping
motors, precision cross-roller bearing slides and proprietary worm gear
capstan drives form the basis of the watch-like mechanical system. The
controller provides power to the stage motors with a quiet linear power
supply to minimize electrical noise radiation in your setup. Pipette holders
and headstages are securely mounted to the MP-285 with one of our
several unique and rigid mounting systems.

The MP-285 was designed to meet a wide variety
of positioning needs for the scientific community, and is suitable for
patch clamp experiments, extracellular recording, microinjection, intra-cellular
recording and precision robotic positioning applications. An outstanding
feature of this system is the unique definable 4th axis for diagonal advancement
of the pipette. You select the angle, then activate the 4th axis. As with
the other three axes, you may move with adjustable coarse or ultrafine
resolution, select the movement speed, and move continuously or in single
step increments. To quickly reposition the pipette, simply select the
Home function. Axes positions are continuously shown in relative and absolute
scales, and are easily readable on the vacuum fluorescent display.
The extremely low backlash of the MP-285 removes traditional drawbacks
of open loop technology and eliminates drift. This allows
submicron resolution down to 0.2 microns in the coarse range and down
to 40 nano-meters in the fine range. With over 1 inch of motorized travel
on all three axes, and a user designated 4th axis, the MP-285 allows
tremendous range of motion while maximizing resolution.
Available with a table-top or rack mounted controller, our manipulator
fits in seamlessly with your other components while the compact design
and assignable axes of the MP-285 allows you to easily integrate
it into your setup at any orientation. To add to its practicality, your
choice of one of two manual controls: joystick or rotary optical encoder
(ROE), assures a comfortable experimentation environment, customized to
For users who require repeatable motion sequences, the MP-285 features
easily programmed robotic control from the keypad, or via a remote computer.
The system can store up to 500 position instructions, including pauses,
and will execute the instruction set once, continuously, or in reverse.
As always, our technical support team is available to address your concerns
and answer all questions before, and after your purchase.
Choose one of two Input Device Options
1) Rotary Optical Encoder (ROE). Turning one of three 2-inch knobs
produces a movement along one axis proportional to the amount and speed
of the turn. Buttons allow the activation of 4th axis, change
of movement resolution, home return function, and toggle between
continuous pulse movements.
2) Joystick. Our joystick is a modified three-axis game controller.
The degree of handle deflection determines the velocity of movement of
each axis. In pulse mode, a button commands the manipulator to take a
single step in the axis selected by joystick deflection.
