Spring Balance Tubular
Product Code : SCL-PLE-11785
The StemAids Tubular Spring Balance is a precision-calibrated force measurement instrument engineered for the empirical study of Hooke’s Law, weight, and friction. Optimized for Primary and Secondary science laboratories, its enclosed "tubular" design protects the internal spring from over-extension and external interference. Manufactured to ISO 9001:2015 standards, it provides a cost-effective, durable solution for quantifying forces in Newtons and masses in Grams.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Force-Mass Interface: Facilitates student understanding of the relationship between mass (m) and weight (W=mg), supporting Mechanics Module 101.
- Hookean Quantification: Enables the physical study of elasticity, allowing learners to apply data to verify Hooke's Law (F=kx) by measuring spring extension against known loads.
- Vector Resolution Analysis: Supports the analysis of forces in equilibrium; used in pairs to demonstrate the resolution of forces on a friction board or inclined plane.
- Calibration Evaluation: Allows students to evaluate and correct for "zero error," fostering high standards of experimental accuracy and instrument maintenance.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade bulk packaging featuring individual poly-bags and shock-resistant internal dividers to ensure springs are not jostled or stretched during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a datasheet specifying the Spring Constant (k) for each model.
- Durability: Tropicalized design featuring corrosion-resistant internal components, ensuring the spring remains responsive and the scale remains legible in high-humidity laboratory environments.
Direct OEM Sourcing Advantages
Procuring the StemAids Tubular Spring Balance directly ensures vertical manufacturing control:
- In-House Spring Tempering: Every spring is batch-tested for linearity across its entire range to ensure the scale remains accurate from the first gram to the last.
- Precision Scale Alignment: Direct oversight ensures the zero-point is easily reachable via the adjustment mechanism, critical for accurate student results.
- Direct Factory Spares Availability: Guaranteed availability of specialized load-hook attachments and replacement transparent tubes to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of the UV-printing process ensures high-contrast markings that will not wear off or fade with repeated laboratory use.
