MP-285
Motorized Micromanipulator
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 the scientist.
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.
