Physical Balance 250gm
Product Code : SCL-PLE-11756
The StemAids Physical Balance (Analytical Type) is a high-sensitivity mechanical weighing instrument engineered for the empirical determination of mass through the principle of moments. Optimized for Secondary and University-level chemistry and physics, this balance provides a precision of 1mg to 5mg (depending on calibration). Manufactured to ISO 9001:2015 standards, it facilitates the quantification of chemical reagents and the verification of Archimedes' Principle within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Gravimetric Statics Interface: Facilitates student visualization of the Law of Moments, supporting Mechanics and General Physics Module 101.
- Mass Quantification: Enables the physical study of matter, allowing learners to apply precision weighing techniques to determine the density of irregular solids and liquids.
- Null-Point Analysis: Supports the analysis of equilibrium by utilizing the central pointer and scale to achieve absolute balance between known and unknown masses.
- Environmental Error Evaluation: Allows students to evaluate the impact of air currents and friction on measurement precision, fostering high-standard laboratory habits.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring "Double-Box" architecture with high-density foam molding to protect the agate knife edges and glass panels from vibrational stress during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and an Assembly & Leveling Guide.
- Durability: Tropicalized design featuring anti-corrosion coatings and vacuum-seasoned wood to prevent warping in high-humidity climates.
Direct OEM Sourcing Advantages
Procuring the StemAids Physical Balance (250g) directly ensures vertical manufacturing control:
- In-House Knife-Edge Grinding: Every agate bearing is polished to a microscopic edge to ensure the balance responds to the smallest fractional weights (milligrams).
- Batch-Tested for Uniform Reliability: Every unit is tested for "Zero-Return" to ensure the beam returns to its original equilibrium point after the load is removed.
- Direct Factory Spares Availability: Guaranteed availability of replacement agate bearings, hangers, stirrups, and leveling screws to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of the beam graduation and plumb-line alignment ensures that students have a reliable reference for absolute horizontal leveling.
