The MP-225 is one of the newer members
in the Sutter Instrument micromanipulator line. Production and design
changes have allowed us to produce a motorized manipulator that is a more
affordable alternative to the industry standard MP-285. While the 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 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 MP-225. Like the 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.
