Narishige MA-2 Micromanipulator Stand

Overview

The Narishige MA-2 Micromanipulator Stand is an engineered mechanical support platform designed specifically for high-precision electrophysiology, microinjection, patch-clamp, and intracellular recording setups. It serves as a rigid, vibration-damping base for Narishige and third-party motorized or manual micromanipulators—ensuring positional stability during sub-micron manipulations under optical microscopy. Unlike generic mounting brackets, the MA-2 integrates a low-profile, cast-aluminum chassis with optimized mass distribution (2 kg) to suppress resonant frequencies commonly induced by environmental vibrations or stage motion. Its design adheres to the mechanical interface standards used across Narishige’s MO-series and MM-series manipulators, enabling direct bolt-down integration without adapter plates. The stand does not incorporate active electronics, actuators, or sensors; it functions purely as a passive, static support system—making it compliant with electromagnetic compatibility (EMC) requirements in shielded Faraday cages and low-noise electrophysiology suites.

Key Features

• Compact footprint (250 × 150 × 85 mm) enables seamless integration into space-constrained rigs—including inverted microscope stages, laminar flow hoods, and custom-built electrophysiology workstations.
• High-rigidity aluminum alloy construction ensures long-term dimensional stability and resistance to creep or thermal drift under continuous load.
• Pre-drilled M4 threaded mounting holes on baseplate and vertical column conform to ISO 2768-mK general tolerances, facilitating repeatable alignment with manipulator base adapters.
• Strategically positioned ventilation gaps around the perimeter enhance convective airflow—critical when deployed adjacent to heat-generating equipment such as amplifier racks or LED illumination systems.
• No moving parts or consumables; requires zero calibration or firmware updates—suitable for GLP-compliant core facilities where maintenance logs and traceability are mandated.

Sample Compatibility & Compliance

The MA-2 is mechanically compatible with all Narishige micromanipulators utilizing standard 32-mm-diameter base flanges (e.g., MO-202, MM-32, MN-403), as well as select third-party models including Sutter MP-285 and Scientifica PatchStar systems via optional flange adapters (sold separately). It imposes no restrictions on sample type or biological preparation—functioning equally well with brain slices, cultured neurons, zebrafish embryos, or C. elegans specimens mounted on upright or inverted platforms. While the stand itself carries no electrical certification, its non-conductive surface finish and absence of embedded circuitry ensure full compatibility with IEC 61000-4-2 ESD protection protocols and ISO 14644-1 Class 5 cleanroom environments when installed with appropriate grounding straps.

Software & Data Management

As a purely mechanical support device, the MA-2 does not interface with software, drivers, or data acquisition systems. It introduces no digital latency, communication overhead, or cybersecurity considerations—making it inherently compatible with all existing acquisition platforms (e.g., HEKA PatchMaster, Axon pCLAMP, Spike2, or custom LabVIEW-based DAQ architectures). Its passive nature eliminates the need for FDA 21 CFR Part 11-compliant audit trails, electronic signatures, or version-controlled firmware—reducing validation burden in regulated preclinical research settings governed by OECD GLP principles.

Applications

• Stabilizing micromanipulators during whole-cell patch-clamp recordings in acute brain slice preparations.
• Providing recoil-free mounting for oil-immersion micropipette positioning in dual-patch configurations.
• Supporting multi-axis manipulator arrays in optogenetic stimulation experiments requiring simultaneous light delivery and electrode access.
• Serving as a modular anchor point in automated patch-clamp systems where robotic arm repeatability depends on base rigidity.
• Enabling reproducible setup reconfiguration across shared core facility microscopes—minimizing alignment recalibration between user sessions.

FAQ

Is the MA-2 compatible with Narishige’s hydraulic micromanipulators?
Yes—the MA-2 supports all Narishige manipulators with standardized 32-mm base flanges, including hydraulic models such as the MH-32 and HM-32, provided the mounting hole pattern matches ISO 2768-mK specifications.
Does the stand include vibration isolation feet?
No—the MA-2 is supplied with standard rubber-tipped leveling feet. For enhanced isolation, users may integrate it with external passive isolators (e.g., Newport SP-200 series) or active platforms (e.g., Minus K MK28) using the baseplate’s M4 tapped holes.
Can the MA-2 be mounted vertically on a wall or enclosure panel?
It is not designed for vertical mounting. Its structural integrity and center-of-gravity optimization assume horizontal placement on a flat, level surface meeting ISO 7243 thermal and vibration criteria.
What surface finish is applied to the aluminum housing?
The chassis features a matte anodized coating (Type II, 15–20 µm thickness) per MIL-A-8625F, providing corrosion resistance and non-reflective optical performance in laser-based setups.
