Sutter Instruments MP-225

Motorized Micromanipulator

In Stock

The Sutter MP-225: Early in the development of the Sutter manipulator line, production, machining and design changes allowed us to produce a motorized manipulator that was a more affordable alternative to the industry standard MP-285. At the time, the changes seemed risky, but today the MP-225 is one of out best sellers. While the Sutter MP-225 feature set is less comprehensive than the MP-285, it includes the most popular features with a user interface that is simpler to use. The mechanical design utilizes a miniature stepper motor and integral anti-backlash gear head. Pre-loaded ball bearing slides provide smooth movement throughout the 25mm of travel. The controller uses low-noise, linear-drive output circuitry identical to that found in the MP-285. The methodology for mounting pipette holders and headstages used with the MP-285 has been maintained in the MP-225 to allow for cross compatibility.

The Sutter MP-225 is designed primarily for positioning patch and intracellular recording pipettes. We have retained and refined the features most desired for this type of work. An extended version of the popular rotary optical encoder (ROE) is the sole input device available with the Sutter MP-225. Like the Sutter MP-285, the manipulator has a synthetic 4th axis for diagonal advancement of the pipette; 16 different angles are selectable via DIP switches. Speed and resolution of movement are easily selected with a multiple position thumbwheel, allowing fast/coarse movement and slow/ultra-fine movement in 10 increments. Two commonly used robotic movements have been incorporated for user convenience. A single button press can initiate a move to a Home position for pipette exchange or to a user defined Work position for quick location of the pipette near the recording location. A display on the ROE gives position location. As all controls are located on the ROE, the controller can be moved to a less accessible area of your setup and does not need to occupy prime space in an equipment rack.

As always, our technical support team is available to address your particular needs and answer all questions before and after your purchase.
