Joystick-Controlled Micromanipulator |
||||||||||||||||||
 Specially adapted for use with the Nanoliter Injector (page 45) for oocyte injection and similar applications, this joystick-controlled micromanipulator allows an easy “steering” motion that translates normal hand movement into smooth submillimeter shifts. Viewed microscopically, movement of the tool-tip corresponds naturally to hand movement, so accurate resolution is intuitive and quick. All fine adjustment can be controlled by the joystick. Pivoting forward, backward, or laterally gives precise x-y adjustment. For added convenience, a separate coarse control lever is also provided for quick raising and lowering. . |

A stop screw—which is set once resolution is achieved—eliminates refocusing and streamlines repetitive work by guiding the tip to its previous focussing plane. The stop screw also prevents the tool-tip from being broken during sudden lowering and eliminates downward drift—placement is stable enough for even extended use. Because the probe holder tilts a full 90°, the tool-tip pivots easily for precise positioning. Rack-and-pinion drive, V-shaped guideways, and cross roller bearings eliminate backlash, slipping, and sticking. All contact parts milled of hardened steel for precise performance and long life. Travel: x-axis, 37 mm; y-axis, 20 mm; z-axis, 25 mm. Joystick travel: 0.35 mm to 3.5 mm, depending on reduction gear ratio setting (adjustable between 1:15 and 1:150) |
