SU-MP285 Motorized Micromanipulator Systems

Options

The SU-MPC385 System consists of the 505093 controller and one to four SU-MP285 micromanipulators.

505093 Controller and ROE

Neurobiological experiments are becoming more complex. Many require multiple manipulators with control units that quickly become space and/or cost prohibitive. The 505093 is the solution you have been asking for. A single controller capable of running 2 to 4 manipulators. Sutter Instrument has taken the simplicity of the SU-MP225 controller and expanded it to run two manipulators from a single controller/ROE. The 505093 works with one or two of our world-renowned mechanicals, the SU-MP285 (SU-MPC385), the SU-MP225 (SU-MPC325) or the narrow format MP-865 (SU-MPC365).

If two manipulators aren't enough, a second controller can be daisy chained to allow the single 505093 to move up to four manipulators. Thus the system can be easily expanded to control highly sophisticated experiments.

The Sutter 505093 is electrically quiet. Unlike the competition, our multi-unit controller employs linear output circuitry. Sutter adds additional manipulators to the same controller without requiring potentially noisy chopper drives.

In all our manipulators, the 4th axis can be set up and changed without the need to connect an external computer to download and configure software. A separate configuration is allowed for each output on this manipulator controller. If desired, each manipulator can approach the prep at a different angle from the horizontal. The 4th axis can be configured between the X and Z axes or the Y and Z axes (useful when manipulator is rotated 90 degrees relative to the preparation).

Faster automated pipette exchange. The 505093 has faster “Home” and “Work Position” moves for quicker pipette exchange. Automation is set up and run via the same interface used in the SU-MP225 controller; however, the speeds of the automated movement are much faster.

Accelerated manual mode. For users who prefer manual pipette exchange we have added “Accelerated Mode” to the ROE. Using Accelerated Mode, the user can make quick manual moves in and out of a setup. Accelerated Mode amplifies the speed attainable in a manual move by smoothly accelerating to the maximum speed during sustained, fast turns of the ROE. Accelerated movement ends as soon as the user stops turning the knob. This mode can be fully disabled for those who feel the need for direct control of the pipette.

505088 Micromanipulator

One of the first in our line of precision motorized micromanipulators, the SU-MP285 mechanical 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. Pipette holders and headstages are securely mounted to the SU-MP285 with one of our several unique and rigid mounting systems.

The extremely low backlash of the SU-MP285 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 63 nanometers in the fine range. With over 1 inch of motorized travel on all three axes, and a user designated 4th axis, the SU-MP285 allows tremendous range of motion while maximizing resolution.

Additional components can be added at any time, allowing the user to develop a system tailored to his or her particular needs. The controller is self-detecting so there is no need for manual configuration of the components.
