Daniel Cell
Product Code : SCL-PLE-11789
The JLab India Daniell Cell is a precision-engineered primary electrochemical cell designed for the empirical study of stable electromotive force (EMF) and non-polarizing chemical reactions. Optimized for Secondary and University-level physics and chemistry, this "two-fluid" cell provides a constant potential of approximately 1.08V. It serves as the classic benchmark for studying redox reactions and the "standard cell" method in potentiometer experiments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Redox Interface: Facilitates student visualization of simultaneous oxidation and reduction, supporting Electrochemistry Module 101 by demonstrating how chemical energy is converted to electrical energy.
- EMF Stability Quantification: Enables the physical study of steady-state voltage, allowing learners to apply the cell in potentiometer circuits to calibrate other instruments without the voltage drop seen in Leclanché cells.
- Depolarization Analysis: Supports the analysis of "self-depolarization"; students observe how the copper ions in the CuSO4 solution prevent hydrogen gas buildup on the cathode, maintaining a constant current.
- Standardization Evaluation: Allows students to evaluate the impact of electrolyte concentration on the cell’s EMF, providing a practical application of the Nernst Equation.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). The copper vessel is protected from oxidation with a removable protective coating, and the fragile porous pot is secured in specialized shock-absorbing foam.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a Safety Data Sheet (SDS) for CuSO4 and H2SO4.
- Component Readiness: All metallic parts are high-purity grade to minimize "local action" currents that can degrade performance during student experiments.
Direct OEM Sourcing Advantages
Procuring the JLab India Daniell Cell directly ensures vertical manufacturing control:
- High-Conductivity Copper: The vessel is manufactured from electrolytic grade copper to ensure minimal internal resistance and maximum surface area for the cathode reaction.
- Precision Porous Barrier: Every porous pot is batch-tested for its diffusion rate, ensuring that ions can move freely while preventing the rapid contamination of the two electrolytes.
- Direct Factory Spares Availability: Guaranteed availability of replacement zinc rods, replacement copper vessels, and pre-measured chemical reagent packs to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of the brass terminal assembly ensures robust electrical contact, preventing loose connections during sensitive balance-point measurements.
