Narishige's NMN-21 is a manually operated micromanipulator which minimizes jitter for simplicity and high performance.

Drift and electromagnetic disturbance are critical problems in patch clamping work. This mechanical micromanipulator was developed specifically for patch clamping: it does not employ a liquid hydraulic system (which is prone to drift caused by temperature changes), has no springs (a common cause of mechanical drift), nor a motor (which can be a source of electrical noise). Its body is designed to absorb vibrations, so that even at high magnifications, problems of jittering are virtually non-existant. The NMN-21 is based on a drum type design and utilizes pairs of sliders for each axis that serve to isolate vibrations caused then a user touches the control knobs from the movement of the device. High mass and a low center of gravity provide exceptionally steady and stable performance. The overall design is compact, so installation requires a minimum of space. With coarse and fine manipulators integrated into the compact body, this model handles a full range of required motions, from moving a microelectrode into the microscope field of view to making delicate contact with cells.

* Can be mounted directly on an optical bench-type isolation table
* Can be firmly fixed to any part of a steel isolation table with the NMN-C magnetic stand (sold separately)
* Can be mounted directly to microscopes via suitable adapters (sold separately)
* AP-14/AP-13-3 patch clamp headstage holders can be attached via the integrated UST-2 solid universal joint
