Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Precision-Matched Brass Tolerances. Outcome: Enables students to calculate the coefficient of linear expansion, supporting "Apply" level proficiency in Thermodynamics Module 2.0.
Feature: Low-Conductivity Insulated Handles. Outcome: Ensures operator safety during high-heat exposure, allowing for focused observation of material state changes (Understand/Analyze).
Feature: High-Purity Metallic Composition. -Outcome: Provides consistent volumetric expansion rates across multiple trials, allowing students to evaluate the reliability of experimental data (Evaluate).
International Logistics & Compliance
To meet the requirements of international procurement tenders, this Educational Instrument is prepared in export-grade seaworthy crating (ISPM-15 compliant) to prevent transit damage. Documentation provided with each shipment includes the Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ Certification for institutional accountability, and technical User Manuals in English. The apparatus features a tropicalized design, tested for structural stability and oxidation resistance in environments reaching 45°C/90% Humidity.
Why Source from the OEM?
Sourcing directly from the OEM ensures vertical integration of the production cycle—from in-house brass casting and precision lathe-turning to final calibration. This eliminates the "Trader" margin and guarantees batch-tested uniformity across thousands of units. We provide direct factory spares availability and technical support, ensuring long-term utility for national-scale educational rollouts. Our facility specializes in high-tolerance machining, ensuring that the "fit-to-fail" ratio remains consistent with rigorous laboratory requirements.
