Rheostat 6 Inches
Product Code : SCL-PLE-11803
The StemAids 6-Inch Sliding Rheostat is a precision-engineered electrical component designed for the empirical study of current regulation in space-constrained laboratory environments. Despite its compact 6-inch (approx. 150mm) form factor, it maintains high-fidelity resistance-to-length linearity, making it ideal for individual student workstations and portable experimental kits. Manufactured to ISO 9001:2015 standards, it provides a robust interface for quantifying Ohm’s Law and demonstrating the principles of potential division.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Resistance Interface: Facilitates student visualization of how conductor length affects electrical resistance (R=ρL/A), supporting the core curriculum of Electromagnetism Module 101.
- Current Quantification: Enables the physical study of circuit control, allowing learners to apply variable resistance to observe the inverse relationship between resistance and current flow.
- Potential Division Analysis: Supports the analysis of voltage regulation; by utilizing all three terminals, students can create a continuously variable potential divider for sensitive electronic experiments.
- Experimental Evaluation: Allows students to evaluate the power-handling capabilities of different wire gauges by monitoring heat dissipation during high-current regulation.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring "Double-Cushion" foam molding. The small footprint allows for high-density packing, significantly reducing per-unit shipping costs for large institutional tenders.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a datasheet specifying maximum wattage and current limits.
- Durability: Tropicalized design featuring anti-oxidation coatings on the resistance wire and corrosion-resistant hardware to maintain precision in high-humidity laboratory environments.
Direct OEM Sourcing Advantages
Procuring the StemAids 6-Inch Rheostat directly ensures vertical manufacturing control:
- High-Purity Ceramic Core: Every ceramic tube is batch-tested for thermal shock resistance, ensuring the core remains structurally sound even when the resistance wire reaches high temperatures.
- Precision Wire Tensioning: Direct oversight of the winding process ensures that the wire turns are perfectly uniform and tight, preventing "dead zones" or erratic resistance jumps during adjustment.
- Direct Factory Spares Availability: Guaranteed availability of replacement slider brushes, insulated knobs, and ceramic cores to maximize the long-term ROI of laboratory assets.
- Manufacturing Control: Direct oversight of the terminal-to-wire connection ensures negligible contact resistance, providing students with accurate and repeatable data for their electrical experiments.
