Daniel Cell Substitute 1.08V
Product Code : SCL-PLE-11852
The StemAids Daniell Cell Substitute is a high-stability electronic voltage reference engineered to provide a constant 1.08V DC output, replicating the standard Electromotive Force (EMF) of a traditional chemical Daniell Cell. Unlike wet cells, this solid-state substitute eliminates the maintenance, chemical hazards, and voltage fluctuations associated with copper-sulfate and zinc-sulfate solutions. Manufactured to ISO 9001:2015 standards, it is an essential calibration tool for University physics laboratories using potentiometers and bridges.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Electrochemistry Interface: Facilitates student understanding of standard electrode potentials without the mess of chemicals, supporting the study of the Nernst Equation and Cell EMF.
- Potentiometric Quantification: Enables the physical calibration of wire potentiometers; learners apply the 1.08V as a known standard to determine the "Potential Gradient" (k) along the wire.
- EMF Comparison Analysis: Supports the analysis of unknown sources; students evaluate the ratio of balancing lengths (l1/l2) by comparing an unknown cell against the 1.08V substitute.
- Reliability Evaluation: Allows students to evaluate the benefits of electronic references over chemical cells, specifically regarding internal resistance and shelf-life stability.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy packaging (ISPM-15 compliant). The unit is housed in a moisture-proof anti-static bag to protect the precision electronics during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a certificate of calibration verifying the 1.08V output.
- Durability: Tropicalized design featuring coated PCBs to prevent oxidation of high-impedance paths, ensuring the reference remains accurate in high-humidity laboratory settings.
Direct OEM Sourcing Advantages
Procuring the StemAids Daniell Cell Substitute directly ensures vertical manufacturing control:
- Precision Calibration: Each unit is trimmed using a 6.5-digit multimeter to ensure the output is exactly 08V at 25?C.
- Low Internal Impedance: Unlike chemical cells which "sag" under load, our electronic substitute maintains a steady potential, ensuring consistent null-points on a potentiometer.
- Direct Factory Spares Availability: Guaranteed availability of replacement battery clips, safety terminals, and internal reference ICs to maximize the long-term ROI.
- Maintenance-Free Design: Eliminates the need for purchasing and disposing of toxic copper/zinc sulfates, significantly reducing the laboratory's recurring operational costs.
