Maxwell Vibration Needle
Product Code : SCL-MH-11943
The Maxwell Vibration Needle is a precision-engineered analytical instrument designed for the determination of the modulus of rigidity of metallic wires using the dynamical method.1 Compliant with university-level physics curricula and ASTM-equivalent mechanical testing standards, this apparatus utilizes inertial oscillation to provide high-resolution torsional shear data. It is optimized for Advanced Secondary and Tertiary engineering laboratories.

Key Pedagogical Outcomes (Bloom’s Taxonomy)
Variable Mass Configuration: Allows students to manipulate the moment of inertia by alternating the positions of solid and hollow cylinders, facilitating the Analysis of torsional oscillation periods.
Vernier-Calibrated Sliding Weights: Supports Precision Measurement competencies by enabling accurate longitudinal positioning of masses along the graduated tube.
Dynamic Modulus Calculation: Connects hardware-generated oscillation data to the mathematical derivation of Rigidity Modulus , supporting the Application of Hooke's Law in three dimensions.
Reference Mirror Integration: Facilitates the Evaluation of experimental error by providing a stable optical datum for counting high-frequency oscillations.2
International Logistics & Compliance
Our manufacturing protocols ensure that every unit is prepared for global distribution and long-term deployment in varied climates.
Packaging: Standardized in export-grade, seaworthy crating (ISPM-15 compliant) to prevent transit-induced calibration shifts.
Documentation: Shipments include a Manufacturer’s Authorization Form (MAF), Certificate of Conformance, and comprehensive technical manuals in English.
Environmental Durability: Tropicalized design featuring corrosion-resistant brass and powder-coated steel, laboratory-tested for continuous operation in environments up to 45°C and 90% humidity.
Why Source from the OEM?
Procurement through our vertical manufacturing chain eliminates the technical discrepancies common with third-party traders. Our facility maintains direct control over metallurgical tolerances, ensuring that the internal bore of the 40cm tube and the external diameter of the 10cm mass inserts are machined to a matched-pair interference fit. By managing the in-house assembly of optical components and chuck-vice alignment, we guarantee structural concentricity—a critical factor in reducing dampening effects during oscillation. Buyers benefit from direct factory spares availability, including replacement wires and mass sets calibrated to the original instrument's specifications.
