In contrast to manipulators, such as the various remote pipetters and other varied types of large size manipulators employed in radiochemical and other radiation laboratories for handling large objects, micromanipulators are mechanical devices especially designed for holding and guiding delicate microtools used for handling minute samples in the field of the microscope at the required magnification. Thus tiny objects and very small amounts of liquids may be subjected under the microscope to a wide range of delicate operations with the aid of micropipets, microneedles, microelectrodes, micromagnets and other varied types of microtools, p. 136. These microtools are inserted in suitable tool holders which are firmly mounted on the micromanipulator by means of suitable clamps and thus are mechanically guided along the three spatial coordinates. In addition to the three-dimensional movement, which may not be enough for certain types of operations, some instruments incorporate revolving or tilting arrangements, to permit greater flexibility of motion.
