Complete Narishige Micromanipulation Catalog


MM-3 Micromanipulators are devices to scale down macroscopic hand movements into microscopic movements of a needle or probe. A variety of technologies are available to accomplish this.  Mechanical micromanipulators (also called direct-drive micromanipulators) use gears to scale down the movement. Hydraulic micromanipulators can also use gears and cantilevers to effect movement but also use the movement of hydraulic fluid from a cylinder of smaller cross-sectional area to a cylinder of larger cross-sectional area to scale down displacement.  Electrical motor-drive micromanipulators use the same gear down principles of mechanical micromanipulators, but use high-precision motors to turn the gears.  Electronic piezo-electric micromanipulators use the expansion of a piezo-electric crystal to effect microscopic movement.  Mechanical micromanipulators have the advantage of being self-contained.  Hydraulic and electric micromanipulators have the advantage of physically isolating the input hand movements from the output microscopic movements via hydraulic lines or electric wires.  This isolation reduced the chances of vibrations being transmitted from the user to the microscope.  An important consideration in all these micromanipulators is to reduce drift due to thermal expansion of the parts.  Typical uses for micromanipulators include Intra-Cytoplasmic Sperm Injection, (ICSI) microinjection of DNA and other substances into cells, nuclear transplantation (cloning) and the positioning of microscopic electrodes on the surfaces of cells for electrophysiological measurements (patch clamping).
