Leclanche Cell 1.5V
Product Code : SCL-PLE-11788
The StemAids Leclanché Cell is a high-stability primary electrochemical cell engineered for the empirical study of ion transfer, chemical energy conversion, and internal resistance. Optimized for Secondary and University-level physics and chemistry, this "wet cell" configuration provides a transparent environment for observing the depolarization process and the generation of electromotive force (EMF). Manufactured to ISO 9001:2015 standards, it facilitates the quantification of cell dynamics without the "black box" limitations of modern dry batteries.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Electrochemical Interface: Facilitates student visualization of the internal components of a battery, supporting Electrochemistry and Current Electricity Module 101.
- EMF Quantification: Enables the physical study of potential difference, allowing learners to apply the Potentiometer method to determine the precise EMF (5V) and internal resistance (r).
- Depolarization Analysis: Supports the analysis of the role of Manganese Dioxide; students can observe how the cell's voltage drops under load and recovers as the MnO2 oxidizes hydrogen gas.
- Ion Migration Evaluation: Allows students to evaluate the impact of electrolyte concentration on current output, fostering a deeper understanding of ionic conductivity.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). Components are packed separately (dry) to prevent chemical reactions during transit, with the glass jar protected by high-density shock-absorbing foam.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a Safety Data Sheet (SDS) for handling MnO2 and NH4Cl.
- Shelf Stability: Components remain chemically inert until the electrolyte is added by the instructor, ensuring a multi-year shelf life in laboratory storage.
Direct OEM Sourcing Advantages
Procuring the StemAids Leclanché Cell directly ensures vertical manufacturing control:
- In-House Porous Pot Testing: Every porous pot is batch-checked for specific porosity levels to ensure efficient ion exchange while preventing the rapid mixing of the depolarizer and electrolyte.
- High-Purity Electrodes: Zinc rods are provided with a high-purity composition to minimize "local action" and ensure steady current delivery.
- Direct Factory Spares Availability: Guaranteed availability of replacement zinc rods, carbon rods, pre-mixed depolarizer packs, and porous pots to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of the carbon rod density ensures low internal resistance and optimal contact with the cathode terminal.
