Eppendorf InjectMan 4 Motorized Micromanipulator for Precision Microinjection

The Eppendorf InjectMan 4 is a motorized micromanipulator designed for precise microinjection into adherent cells, small organisms, and embryos. It supports dynamic movement via joystick control and integrates with FemtoJet microinjectors for semi-automatic injections. Key features include:

• Axial injection movement (X/Z direction) minimizes mechanical stress and reduces cell mortality.
• High penetration speed facilitates injection into rigid structures.
• Four pre-defined application masks plus a programmable "My app" mask for customized workflows.
• Electronically uncouplable motor modules prevent accidental micropipette movement.
• Exceptional precision and position stability suitable for patch clamp applications.
• Ergonomic control panel for fatigue-free operation and easy angle adjustments.
• Compatibility with Eppendorf PiezoXpert for piezo-assisted penetration at predefined distances.
• Adaptability to all conventional microscopes.
• PC interface for remote control via serial port (SUBD9, male).

Technical Specifications:

• Max traveling distance: ≥20 mm in X, Y, Z, and X/Z directions
• Step size: <20 nm (computational resolution)
• Speed range: 0 – 10,000 µm/s
• Mechanical adjustability: >80 mm
• Motor modules: Stepper motors for X, Y, Z axes
• Dimensions:
• Motor modules: 129 × 51 × 36 mm, 570 g each
• Control board: 205 × 288 × 152 mm, 1.8 kg
• Complete system weight: 2.15 kg
• Swivel joint rotation: -45° to +90° (forward rotation for capillary exchange, backward for sample replacement)
• Angle head operating range: 0° – 90°
• Control: Joystick with dynamic kinetics and speed modes (coarse, fine, x-fine)

Applications include:

• Semi-automatic microinjection of adherent cells
• Serial microinjection into fish larvae, frog eggs, insect embryos
• Injection into living plant cells, C. elegans, nematodes, and flatworms
• Automatic dispensing of cell suspensions and solutions
• Stable, drift-free positioning for electrophysiology techniques

The InjectMan 4 is intended for research use only.
