Motorized Micromanipulator Sutter MP-225

The MP-225 is a more affordable option than the MP-285 and MPC-365. This motorized manipulator was created in 2002 as a more cost-effective substitute for the MP-285, the industry standard. This was made possible by modifications to manufacture and design. Despite having a smaller feature set than the MP-285, the MP-225 nevertheless has the most frequently used functionality and an effective user interface. An integrated anti-backlash gear head and a tiny stepper motor are employed in the mechanical design. The 25 mm of travel is made smooth by pre-loaded ball bearing slides. The controller incorporates linear-drive output circuitry with low noise, the same as that used in the MP-285. For cross compatibility, the mounting procedure for pipette holders and headstages utilized with the MP-285 has been carried over to the MP-225.

The MP-225 is primarily intended for patch and intracellular recording pipettes positioning. The characteristics that are most wanted for this kind of job have been kept and improved. The MP-225 only has one input option, an enlarged version of the well-known rotary optical encoder (ROE). The manipulator, also like the MP-285, includes a synthetic fourth axis for the pipette to advance diagonally; 16 different angles are configurable via DIP switches. A multiple position thumbwheel makes it simple to choose between fast/coarse movement and slow/ultra-fine movement in increments of 10. For the convenience of the user, two frequently utilized robotic movements have been included. The pipette may be quickly located close to the recording place by moving to a user-defined Work position or moving to the Home position with a single button click. Position location is provided by a display on the ROE. The controller does not need to take up valuable space in an equipment rack because all controls are situated on the ROE, which can be moved to a less favorable location in your system.

As always, Sutter technical support staff is ready to attend to your specific requirements and handle any queries you may have both before and after your purchase.
