The NEW M-Prep 6x™ grinding/polishing machine is designed for manual sample preparation. The powerful, quiet motor provides constant high-torque output throughout the speed range, in either 10-500 or 20-1,000 RPM configurations. Touchpad controls activate coolant flow (adjustable) and start/stop. A 7" color LCD touchscreen with keypad entry is used to control all functions with an intuitive interface optimized for efficiency. Five (5) user-defined preset buttons allow quick and easy RPM selections in either clockwise or counterclockwise rotation.
