NARISHIGE UX-4-10 X-Block

Overview

The NARISHIGE UX-4-10 X-Block is a precision-machined mechanical coupling component engineered for high-stability, multi-axis alignment in micro-manipulation systems used in electrophysiology, patch-clamp recording, microinjection, and single-cell manipulation. Unlike general-purpose brackets or adaptors, the UX-4-10 is purpose-built to enable orthogonal, rigid, and repeatable fixation of two dissimilar-diameter micromanipulator rods—specifically a Ø4 mm support rod and a Ø10 mm actuator rod (e.g., USM-10)—within the standardized NARISHIGE modular manipulator architecture. Its operation relies on mechanical interference fit and calibrated clamping force rather than magnetic or adhesive bonding, ensuring long-term dimensional stability under repeated thermal cycling and mechanical vibration typical in vibration-isolated optical tables and Faraday cages. The block’s compact monolithic design (36 × 12 × 26 mm, 22 g) minimizes moment arm effects and inertial loading on fine-positioning stages, directly contributing to sub-micrometer positional reproducibility during extended experimental protocols.

Key Features

• Precision-machined anodized aluminum alloy construction ensures corrosion resistance, non-magnetic compatibility, and dimensional stability across laboratory temperature ranges (15–30 °C)
• Dual-bore geometry with precisely aligned perpendicular bores: Ø4.0 ± 0.01 mm (for standard NARISHIGE SM series rods) and Ø10.0 ± 0.02 mm (for USM-10 or equivalent actuator rods)
• Integrated M2.6 threaded mounting holes conforming to NARISHIGE’s universal baseplate interface standard (pitch = 12 mm grid), enabling tool-free reconfiguration on XY translation stages or custom optical breadboards
• Zero-backlash clamping via dual-set-screw configuration—each bore features two opposing M2.6 screws with knurled heads for tactile torque control and consistent preload without slippage
• Minimal footprint and low center-of-gravity design reduce resonance frequency coupling with piezoelectric or hydraulic manipulators, supporting stable positioning at <1 µm RMS drift over 8-hour recordings

Sample Compatibility & Compliance

The UX-4-10 X-Block is exclusively compatible with NARISHIGE’s ecosystem of micromanipulators, including but not limited to the MO-202, MN-403, and MP-285 series, as well as third-party systems adhering to the Ø4 mm / Ø10 mm rod diameter standard (e.g., Sutter Instrument MPC-200-compatible mounts). It complies with ISO 9001-certified manufacturing controls applied at NARISHIGE’s Chiba production facility. While not a standalone analytical instrument, its mechanical performance supports GLP- and GMP-aligned workflows where traceable hardware configuration is required—for example, in preclinical neurophysiology labs subject to FDA 21 CFR Part 11 audit requirements for equipment qualification records. No electrical, optical, or fluidic interfaces are present; therefore, no IEC 61000-4 immunity testing or RoHS exemption declarations apply.

Software & Data Management

As a passive mechanical adapter, the UX-4-10 X-Block requires no firmware, drivers, or software integration. Its function is independent of host computer systems, data acquisition hardware (e.g., Axon Digidata, HEKA EPC), or control platforms (e.g., PatchMaster, Spike2). However, its precise geometry enables deterministic coordinate mapping between manipulator axes—critical when reconstructing 3D electrode trajectories from motor encoder logs. Lab managers may document its installation state (e.g., orientation angle, torque setting, serial-matched rod pairing) within electronic lab notebooks (ELNs) such as LabArchives or Benchling to satisfy ALCOA+ data integrity principles for regulatory submissions.

Applications

• Orthogonal mounting of a Ø4 mm coarse-positioning rod (e.g., MN-403 base) and a Ø10 mm fine-positioning actuator (e.g., USM-10) in dual-stage patch-clamp rigs
• Stable integration of optical fiber holders (Ø4 mm) with motorized micromanipulators (Ø10 mm) in optogenetics experiments requiring simultaneous light delivery and electrode advancement
• Modular assembly of multi-probe arrays in in vivo silicon probe recordings, where spatial registration between tetrodes and reference electrodes must remain invariant across days
• Custom fixture design for cryo-EM sample holder alignment jigs, leveraging the block’s repeatable angular registration for fiducial-based stage calibration
• Education and training setups in university biophysics labs, where mechanical simplicity and visual clarity support pedagogical objectives in micromanipulation fundamentals

FAQ

Is the UX-4-10 compatible with non-NARISHIGE manipulators?

Yes—if the external rod diameters match Ø4.0 mm and Ø10.0 mm with tolerances ≤ ±0.02 mm, and the mounting interface accepts M2.6 screws on a 12 mm pitch grid.
Can it be used in vacuum or cleanroom environments?

The anodized aluminum surface is compatible with ISO Class 5 cleanrooms; however, outgassing characteristics have not been certified per ASTM E595, so vacuum use below 10⁻⁴ mbar is not recommended.
What torque should be applied to the clamping screws?

NARISHIGE specifies 0.05–0.08 N·m using a calibrated M2.6 torque screwdriver; exceeding 0.1 N·m risks thread deformation and loss of repeatability.
Does the UX-4-10 include mounting hardware?

No—M2.6 × 4 mm stainless steel socket-head cap screws are required separately and are available through NARISHIGE part number SB-264.
How does it differ from the UX-6-10 variant?

The UX-6-10 accommodates Ø6 mm × Ø10 mm rods and has larger outer dimensions (29 × 12 × 31 mm); the UX-4-10 provides higher rigidity-to-mass ratio for applications demanding minimal inertia on fast-response stages.
