MM-33 Micromanipulator

MM-33 — Compact Manual Micromanipulator

The MM-33 from Sutter Instrument is a compact, practical manual micromanipulator designed for applications that require maximum versatility in the smallest possible footprint. Successfully used alongside Sutter's motorized manipulators in complex experiments, and as a stand-alone unit in teaching environments, the MM-33 delivers stable, drift-free manual positioning without the need for motors or electronics.

Key Features

• Stainless steel cross-loaded roller bearings: Pre-loaded at 90° to hardened steel guides — low friction, smooth linear motion, minimal side play
• Precision rack-and-pinion drive: Stable, drift-free movement with minimal backlash; controls placed one above the other for ergonomic, "blind" operation
• Coarse scales: All axes calibrated in 0.10 mm increments
• Fine micrometer X-axis: Calibrated at 0.01 mm with estimates to 5 µm resolution
• Vertical axis lock: Locks the position of the vertical axis, increasing stability during recording
• Compact design: Right choice for tight environments requiring maximum versatility within a small space

Options (factory installed at time of order)

• Rotating base: Adds two extra rotational planes — approximately 120° horizontal rotation (positive stop, quick release for fast pipette insertion/removal) and 0–70° vertical tilt
• Tiltable X-axis: Fine axis tilts up to 45° for angled approaches

Applications

• Teaching and training environments
• Supplementary manipulator alongside motorized systems
• Applications in tight or confined experimental setups
• Coarse positioning where submicron accuracy is not required
