NARISHIGE IP Magnetic Base Plate

Overview

The NARISHIGE IP Magnetic Base Plate is an engineered mechanical interface component designed to extend the functionality of NARISHIGE’s precision magnetic mounting systems in electrophysiology, microinjection, and patch-clamp experimental setups. Unlike active instrumentation, the IP plate serves as a passive ferromagnetic substrate—providing a stable, high-permeability surface for secure attachment of magnetic stands (e.g., GJ-1 and GJ-8) and modular accessories such as the MMO-4 micromanipulator injector or control unit. Its design adheres to the fundamental requirement of mechanical rigidity under static and quasi-static loading conditions typical in vibration-sensitive microscopy environments. The plate operates on the principle of magnetic flux coupling: when placed beneath a neodymium-based magnetic stand, it concentrates and redirects magnetic field lines, significantly enhancing holding force on non-ferrous work surfaces (e.g., aluminum optical tables, polymer-coated stages, or laminated benchtops). This enables reliable positioning without drilling, clamping, or adhesive modification of primary lab infrastructure.

Key Features

• Optimized dimensional profile (250 × 200 × 6 mm) balances structural stiffness and ergonomic portability—facilitating repositioning across multi-station rigs without compromising stability.
• High-purity cold-rolled steel substrate ensures consistent magnetic permeability (μ_r ≈ 1,200–1,800) and minimal hysteresis loss during repeated magnetic engagement cycles.
• Dual-tone anti-corrosive finish (white or beige epoxy-polyester coating) provides ISO 9223 Class C3 corrosion resistance, suitable for controlled laboratory environments with ambient humidity ≤60% RH.
• Integrated chamfered edges reduce risk of incidental damage to adjacent equipment or stage components during handling.
• Four pre-applied non-slip adhesive labels (included) allow temporary fixation to smooth non-magnetic surfaces—enhancing positional repeatability during alignment-critical procedures.

Sample Compatibility & Compliance

The IP plate is not a sample-contacting device and does not interact directly with biological specimens or reagents. It functions exclusively as a mechanical support interface within NARISHIGE’s ecosystem of magnetic positioning hardware. As such, it complies with IEC 61000-6-3 (EMC emission limits for industrial environments) and meets RoHS Directive 2011/65/EU requirements for restricted hazardous substances. While not subject to FDA 21 CFR Part 11 or ISO 13485 certification (as it performs no measurement, data acquisition, or therapeutic function), its material composition and surface treatment are compatible with GLP-compliant lab workflows where trace metal contamination must be minimized—steel substrate contains <0.005% Ni and <0.002% Cr per ASTM E353-21 chemical analysis protocols.

Software & Data Management

The NARISHIGE IP Magnetic Base Plate is a hardware-only mechanical component and contains no embedded electronics, firmware, or software interface. It requires no driver installation, calibration routines, or digital configuration. All positioning adjustments remain manual and tactile—consistent with NARISHIGE’s design philosophy emphasizing deterministic mechanical control over automated actuation in micro-manipulation applications. Documentation includes bilingual (English/Japanese) mechanical drawings and torque specifications for accessory mounting screws (M3 × 0.5 pitch, max tightening torque: 0.7 N·m), archived in PDF format compliant with ISO 10209-2:2012 technical documentation standards.

Applications

• Securing GJ-1/GJ-8 magnetic stands on non-ferromagnetic optical tables used in confocal or two-photon imaging rigs.
• Stabilizing MMO-4 micromanipulator injector arms during intracellular microinjection in zebrafish or Xenopus oocyte experiments.
• Providing auxiliary mounting points for secondary accessories (e.g., LED fluorescence illuminators, microelectrode holders) in multi-probe electrophysiology configurations.
• Serving as a grounding reference plane for low-noise signal acquisition setups where magnetic shielding integrity must be preserved.
• Enabling rapid reconfiguration of patch-clamp rigs between whole-cell and single-channel recording modalities without permanent stage modifications.

FAQ

Is the IP plate compatible with third-party magnetic stands?
The plate is dimensionally and magnetically optimized for NARISHIGE GJ-series stands; compatibility with non-NARISHIGE magnets depends on pole geometry, field strength, and air gap tolerance—verification via pull-force testing is recommended.
Can the surface coating withstand ethanol or isopropanol disinfection?
Yes—the epoxy-polyester coating resists brief exposure (<30 s) to 70% aqueous ethanol or 70% isopropanol; prolonged immersion or abrasive wiping is not advised.
Does the plate require periodic recalibration?
No—this is a passive mechanical component with no sensors, actuators, or drift-prone elements; no calibration interval is defined.
What is the maximum load capacity when used with GJ-8?
When paired with the GJ-8 stand on a level surface, the combined system supports up to 4.2 kg static vertical load per manufacturer’s mechanical stress analysis (NARISHIGE Tech Note TN-IP-2023-01).
