Physical Weight Box Iron 100gm
Product Code : SCL-PLE-11704
The StemAids Physical Weight Box (100g) is a calibrated laboratory mass set engineered for high-precision measurement in elementary mechanics and chemical balancings. Optimized for Secondary and Vocational (TVET) curricula, this set facilitates the quantification of mass, force, and density through the Method of Substitution. Manufactured to ISO 9001:2015 standards, it provides a ruggedized, corrosion-resistant solution for verifying Archimedes' Principle and the Laws of Equilibrium within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Standardized Mass Interface: Facilitates student visualization of discrete mass units and their role in balancing torques, supporting Statics Module 101.
- Gravimetric Quantification: Enables the physical study of mass vs. weight, allowing learners to apply the formula W=mg to determine gravitational force.
- Density Determination Analysis: Supports the analysis of volumetric displacement when paired with a displacement vessel (Eureka Can) for solid object density calculations.
- Measurement Accuracy Evaluation: Allows students to evaluate the impact of buoyancy and surface contamination (skin oils) on high-precision analytical weighing results.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring specialized moisture-barrier lining to protect the iron weights from oxidation during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and internal calibration report in English.
- Durability: Tropicalized design featuring specialized anti-corrosion enameling tested for stability in high-humidity laboratory environments (up to 90% RH).
Direct OEM Sourcing Advantages
Procuring the StemAids Physical Weight Box directly ensures vertical manufacturing control:
- In-House Precision Calibration: Weights are batch-tested against OIML-standard reference masses to ensure accuracy within prescribed tolerance classes.
- Batch-Tested for Uniform Reliability: Every wooden enclosure undergoes a kiln-drying process to ensure the slots remain dimensionally stable and do not warp in varied climates.
- Direct Factory Spares Availability: Guaranteed availability of replacement fractional weights and forceps to maintain complete laboratory sets.
- Manufacturing Control: Direct oversight of the coating process ensures a uniform, non-chip finish, preventing mass loss over thousands of repetitive classroom cycles.
