Torsion Apparatus/Barton's Apparatus (Vertical Pattern)

Product Code : SCL-MH-11947

The Torsion Apparatus (Barton’s Vertical Pattern) is a precision-engineered Educational Instrument designed for the empirical determination of the modulus of rigidity in cylindrical specimens. Compliant with ISO 17025 laboratory standards for metrological consistency, this vertical-mount system is optimized for undergraduate physics and mechanical engineering laboratories. It facilitates high-accuracy shear strain measurements through a three-point circular scale configuration and frictionless load transmission.

Key Pedagogical Outcomes

Feature: 3-Jaw Chuck and Torsional Drum Clamping.

Outcome: Ensures zero-slip boundary conditions during torque application, allowing students to accurately isolate material deformation from mechanical play.

Feature: Multi-Point Sliding Circular Scales.

Outcome: Facilitates the measurement of angular twist at various longitudinal points, enabling the verification of the linear relationship between length and torsion.

Feature: Frictionless Pulley Load Application.

Outcome: Minimizes parasitic torque losses, ensuring that force input data aligns with theoretical calculations for shear stress.

Feature: Interchangeable Test Rods.

Outcome: Allows for comparative analysis of different alloy compositions, supporting Solid Mechanics modules regarding material-specific rigidity constants.

International Logistics & Compliance

Engineered for global distribution, this Educational Instrument is housed in export-grade, seaworthy crating (ISPM-15 compliant) to ensure structural integrity during maritime or air freight. Documentation provided includes the Manufacturer’s Authorization Form (MAF), internal ISO-compliant calibration reports, and comprehensive technical manuals in English. The unit features a tropicalized finish—utilizing powder-coated cast iron and corrosion-resistant alloys—tested for sustained operational accuracy in environments reaching 45°C and 90% humidity.

Why Source from the OEM?

As a vertically integrated manufacturer established in 1946, our production facility maintains total control over the metallurgy and machining of every component. Unlike traders, our "Science City" assembly hub utilizes in-house precision grinding and batch-testing protocols to ensure uniformity across high-volume institutional tenders. Procurement officers benefit from direct factory spares availability, ensuring a product lifecycle exceeding 10 years in active laboratory use.
