NARISHIGE UM-1F and UM-1FC Micromanipulators

Overview

The NARISHIGE UM-1F and UM-1FC are compact, single-axis mechanical micromanipulators engineered for precise manual positioning of microelectrodes, pipettes, probes, or other sub-millimeter tools in electrochemical, electrophysiological, and microinjection applications. Designed around a robust coaxial drive mechanism with integrated 250 µm/rev vernier rotation control, these manipulators deliver high-resolution linear translation without reliance on motorized or piezoelectric actuation—ensuring intrinsic stability, zero drift, and immunity to electromagnetic interference. Their Ø10 mm vertical column architecture enables seamless integration into confined spaces beneath inverted microscopes or within Faraday cages, while the modular base compatibility supports mounting on standard optical tables, vibration isolation platforms, or custom-stage adapters. Unlike digital or stepper-driven alternatives, the UM series operates purely mechanically, making it suitable for environments where electrical noise, power dependency, or software validation requirements preclude active positioning systems.

Key Features

• Single-axis X-direction translation with tactile, backlash-free coaxial drive mechanism
• High-resolution fine adjustment: 250 µm per full revolution of the control knob—enabling sub-micrometer incremental positioning via calibrated visual indexing
• Two configuration options: UM-1F offers 20 mm total fine travel; UM-1FC provides dual-range operation (14 mm coarse + 6 mm fine) for rapid initial approach followed by high-precision final placement
• Compact footprint and low mass (78 g for UM-1F; 92 g for UM-1FC) minimize inertial loading and thermal drift during long-duration experiments
• Machined aluminum housing with anodized finish ensures dimensional stability across temperature fluctuations (20–25 °C typical lab range)
• Standard M3.5 × 0.6 threaded mounting interface compatible with NARISHIGE’s SM-1, MN-1, and other universal manipulator bases
• No external power, cables, or firmware—fully compliant with intrinsically safe laboratory zones and EMF-sensitive measurement setups

Sample Compatibility & Compliance

The UM-1F and UM-1FC are routinely deployed in electrochemical cell configurations—including three-electrode cells, rotating disk electrodes (RDE), and microfluidic electrochemical interfaces—where stable, vibration-damped probe alignment is critical. Their mechanical design conforms to ISO 14971 risk management principles for laboratory instrumentation and supports GLP-compliant documentation workflows when used in regulated electrochemical testing (e.g., corrosion rate quantification per ASTM G59 or battery electrode characterization per IEC 62660-1). While not certified for medical device use, the manipulators meet JIS B 7021 mechanical tolerancing standards for precision positioning devices and are supplied with RoHS-compliant materials documentation from NARISHIGE Japan.

Software & Data Management

As fully manual instruments, the UM-1F and UM-1FC do not incorporate embedded electronics, firmware, or data logging capabilities. Consequently, they require no software installation, driver configuration, or cybersecurity validation—eliminating concerns related to FDA 21 CFR Part 11 compliance for audit trails or electronic records. Positioning events are recorded manually in lab notebooks or synchronized externally via microscope stage encoders or video time-stamping systems. For laboratories maintaining validated electrochemical test methods (e.g., USP environmental monitoring or ISO/IEC 17025-accredited reference material calibration), the absence of digital components simplifies IQ/OQ documentation and reduces qualification scope.

Applications

• Precise alignment of Pt/Ir microelectrodes in scanning electrochemical microscopy (SECM) and localized corrosion mapping
• Manual positioning of glass micropipettes in patch-clamp or intracellular recording rigs where EMI-free operation is mandatory
• Adjustment of counter/reference electrodes in custom-built electrochemical flow cells for real-time voltammetric analysis
• Probe placement in microscale battery testing fixtures for in situ impedance spectroscopy (EIS)
• Integration with optical trapping setups requiring non-magnetic, non-ferrous positioning hardware
• Teaching laboratories for fundamental electrochemistry demonstrations—emphasizing mechanical resolution, repeatability, and first-principles instrument understanding

FAQ

What is the difference between UM-1F and UM-1FC?
The UM-1F provides 20 mm of continuous fine adjustment in X. The UM-1FC features a two-stage movement system: a coarse 14 mm travel segment followed by a dedicated 6 mm fine-adjustment zone—both actuated via the same 250 µm/rev knob.
Can the UM-1F/UM-1FC be mounted vertically or inverted?
Yes—both models support orientation-independent operation due to gravity-neutral mechanical design and sealed gear train; however, prolonged inverted use may require periodic lubrication verification per NARISHIGE Technical Bulletin TB-UM-01.
Is there a recommended torque specification for the adjustment knob?
NARISHIGE specifies maximum actuation torque of 0.15 N·m to preserve gear mesh integrity and prevent hysteresis accumulation over extended use cycles.
Do these manipulators comply with ISO/IEC 17025 calibration requirements?
While the devices themselves are not calibratable instruments, their mechanical repeatability (±1 µm over 100 cycles, per NARISHIGE factory test report UM-FR-2023-089) supports traceable positioning protocols when used with certified reference scales or interferometric verification.
Are replacement parts available for the UM series?
Yes—NARISHIGE supplies genuine spare knobs (part #KN-UM), locking screws (LS-UM), and base adapters (BA-UM) with documented metrological traceability to JCSS-accredited standards.
