TRIO™-245, 3-axis / 0–90° Diagonal Micromanipulator

TRIO™-245 — 3-Axis / 0–90° Diagonal Motorized Micromanipulator

The TRIO™-245 from Sutter Instrument is a next-generation, highly stable 3-axis motorized micromanipulator with 25 mm of travel on the X, Y and Z axes. Its software-configurable synthetic 4th diagonal axis (0–90°) enables coaxial pipette movement without mechanical re-mounting. The TRIO-245 features a compact lead-screw mechanical design with a smaller footprint than most manipulators, making it ideal for setups requiring two pipettes or where table space is limited.

Key Features

• 3 independent axes: 25 mm travel on X, Y and Z
• Synthetic 4th diagonal axis: Configurable in software to any angle between 0 and 90° — no mechanical adjustment needed
• Lead-screw precision design: Smaller overall size and footprint than most manipulators; ideal for multi-pipette setups
• Motor powers down during recording: Eliminates heating effects and electrical noise — delivers the quietest manipulators in the industry
• Zero drift: Sutter manipulators will not drift in the middle of experiments
• Integrated ROE controller: No rack-mounted controller required; compact and fully self-contained
• Position display: Relative and absolute coordinates shown directly on the ROE
• Logarithmic acceleration: Smooth, intuitive speed control proportional to ROE knob rotation — no speed selection needed
• Y-axis lockout: DIP switch selectable; enables X/Z-only movement during HOME and WORK repositioning
• WORK and HOME memory: Store and recall positions for fast pipette exchange
• DIP switch configuration: Reverses ROE directional movement to match user preference
• Dual voltage: 115/230 V, 50/60 Hz; CE certified

Applications

• In vitro patch clamp electrophysiology
• Intracellular sharp electrode recording
• Dual-pipette setups where space is limited
• Any experiment requiring drift-free, electrically quiet micromanipulation
