NIKON MP-285 STATIC SMOOTH DRUM ROLLER

Technical Description

The Nikon MP-285 is a precision static smooth drum roller integrated with a high-performance three-axis motorized micromanipulator system, designed for advanced scientific applications such as electrophysiology and microinjection. The XY mechanical stage provides travel ranges of 2.76 x 1.97 inches, supporting precise sample positioning. Total current magnification ranges from 40x to 200x, with a maximum achievable magnification of up to 1000x when using 10x eyepieces. The micromanipulator offers motorized travel of 1 inch (25 mm) along all three orthogonal axes, with submicron resolution capabilities of 0.2 µm per coarse step and 40 nm per fine step, ensuring exceptional spatial precision. It operates at a maximum speed of 2.9 mm/sec with low mechanical backlash, minimizing drift for stable long-term experiments. The mechanical dimensions of the manipulator are compact at 4.5 x 6 x 6.25 inches, while the controller measures 16 x 10.75 x 3.75 inches. The system features a user-programmable virtual 4th diagonal axis for precise oblique positioning, and continuous relative and absolute positional readouts are shown on an easy-to-read vacuum fluorescent display. Movements can be finely controlled in continuous or discrete step modes, with a Home function for rapid repositioning. Remote computer control is available via serial interface. The device weighs approximately 300 lb, reflecting its robust build tailored for stable placement in electrophysiology and microscopy setups. This combination of precise mechanics, motorized control, and versatile mounting systems makes the Nikon MP-285 a highly reliable tool for intricate manipulations at the microscale.
