Leclanche Cell 1.5V
Product Code : SCL-PLE-11788
The JLab India 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). 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
JLab India 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 JLab India 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.
