Micromanipulators
A micromanipulator positions a microtool — a probe, needle, micropipette or electrode — near a sample under the microscope with a precision far beyond the unaided hand, moving it in fine, controlled increments. Clemex supplies Märzhäuser micromanipulators in manual and motorized versions for applications such as electrophysiology, single-cell injection, probing and micro-dissection.
Manual and motorized versions
Manual
With a manual micromanipulator, the operator positions the tool directly using fine mechanical adjustment controls. Märzhäuser's manual models are built on precise, stable cross-roller bearings that keep working without noticeable wear even after many years of intensive use.
Motorized
Motorized micromanipulators are stepper-motor driven, so the tool no longer has to be fine-positioned by hand and movement is free of vibration. This is well suited to delicate work and to long experiments where a steady, repeatable approach matters.
Key features
- Sub-manual precision for the most demanding work in the micrometer range
- Durable cross-roller bearings for long-term, virtually wear-free smooth motion
- Manual and motorized options — hands-on control, or vibration-free motorized positioning
- Configurable, with left- and right-handed setups and a range of holders, stops and stands
- Suited to electrophysiology, cell injection, probing and micro-dissection
Frequently Asked Questions
What is a micromanipulator?
A device that moves a probe, needle, micropipette or electrode with micrometer-scale precision under a microscope — finer and steadier than the hand can manage on its own.
What is the difference between manual and motorized?
Manual models are positioned by hand via fine mechanical controls. Motorized models use stepper motors, removing hand fine-positioning and enabling smooth, vibration-free movement.
What are they used for?
Electrophysiology, injecting material into single cells, micro-probing and micro-dissection — any task needing precise placement of a tool near the sample.
Why choose motorized over manual?
Motorized positioning is vibration-free and repeatable, which helps with delicate or long experiments. Manual is simpler and needs no controller.
What tools can it hold?
Micropipettes, needles, probes and electrodes, via interchangeable holders and clamps. Accessories such as Z-axis stops, magnetic stands and tilting devices are also available.
