This
was Narishige“s first water hydraulic
micro-manipulator specially designed for patch
clamping. Its water hydraulic system has a lower
coefficient of expansion than an oil hydraulic system
and allows precise movement. A 1:5 cartridge is
incorporated to minimize drifting. The large, rigid
driving unit enables fine movement and coarse
manipulations; a sturdy ball joint is also used.
Installation is made more rigid by securing
attachments to the bar. The drum type control unit has
a large handle for precise operation and high linear
repeatability. Overall, design considerations are
focused on precision movement and stability over long
periods of time. This model set the standards for
subsequent models of micromanipulator for patch
clamping.
