Bob Set Of 6 Metals
Product Code : SCL-PLE-11705
The JLab India Bob Set of 6 Metals is an essential physics demonstrator engineered for the empirical study of material properties, simple harmonic motion (SHM), and thermodynamics. Optimized for Secondary and University-level laboratories, this set provides six geometrically identical spheres (25mm diameter) of varying elemental compositions. It facilitates the quantification of density, specific heat capacity, and the independence of pendulum periods from mass.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Geometric Volume Standardization: Facilitates student visualization of how identical volumes can possess significantly different masses, supporting Density Module 101.
- Pendulum Period Quantification: Enables the physical study of oscillation, allowing learners to apply different bobs to a string to verify that mass does not affect the period of a simple pendulum.
- Specific Heat Analysis: Supports the analysis of thermal energy absorption when bobs are heated in a steam chamber and transferred to a calorimeter.
- Material Property Evaluation: Allows students to evaluate the relationship between atomic mass and macroscopic density by calculating the mass-to-volume ratio (D=m/v) for each element.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) with anti-corrosion VCI (Volatile Corrosion Inhibitor) lining to protect the metallic surfaces during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a reference table of theoretical densities in English.
- Durability: Tropicalized design featuring specialized coatings on the iron and zinc bobs to prevent oxidation in high-humidity climates.
Direct OEM Sourcing Advantages
Procuring the JLab India Bob Set of 6 Metals directly ensures vertical manufacturing control:
- In-House Precision Machining: Every bob is batch-tested for diameter and sphericity to ensure that the volume remains a constant control variable across all experiments.
- Batch-Tested for Uniform Reliability: Suspension hooks are tensile-tested to ensure they remain secure during high-amplitude oscillation demonstrations.
- Direct Factory Spares Availability: Guaranteed availability of individual replacement bobs to maintain complete laboratory sets without re-purchasing entire kits.
- Manufacturing Control: Direct oversight of metallurgical purity ensures that experimental density results align closely with standard periodic table values.
